with Shinzō Abe (at the Prime Minister's Official Residence on October 22, 2014)

Amano was born in Hamamatsu, Japan, on September 11, 1960. He received his BE, ME and DE degree in 1983, 1985 and 1989, respectively, from Nagoya University.

During elementary school days, he played soccer as a goalkeeper and softball as a catcher. He was also passionate about amateur radio and despite hating studying, he was good at mathematics. Upon entering high school, he began taking his studies seriously and became a top student by studying every day late into the night.


From 1988 to 1992, he was a research associate at Nagoya University. In 1992, he moved to Meijo University, where he was an assistant professor. From 1998 to 2002, He was an associate professor. In 2002, he became a professor. In 2010, he moved to the Graduate School of Engineering, Nagoya University, where he is currently a professor.

He joined Professor Isamu Akasaki's group in 1982 as an undergraduate student. Since then, he has been doing research on the growth, characterization and device applications of group III nitride semiconductors, which are well known as materials used in blue light-emitting diodes. In 1985, he developed low-temperature deposited buffer layers for the growth of group III nitride semiconductor films on a sapphire substrate, which led to the realization of group-III-nitride semiconductor based light-emitting diodes and laser diodes. In 1989, he succeeded in growing p-type GaN and fabricating a p-n-junction-type GaN-based UV/blue light-emitting diode for the first time in the world.

Known to be keen on research, Amano's laboratory was always lit late at night, such as weekdays, holidays, New Year's Day, and was called "no night castle".[3] According to his students in the laboratory, Amano has an optimistic and temperate personality, and is never angry.[4][5]

Blue laser

A blue laser is a laser that emits electromagnetic radiation with a wavelength between 360 and 480 nanometres, which the human eye sees as blue or violet.

Blue beams are produced by helium-cadmium gas lasers at 441.6 nm, and argon-ion lasers at 458 and 488 nm. Semiconductor lasers with blue beams are typically based on gallium(III) nitride (GaN; violet color) or indium gallium nitride (often true blue in color, but also able to produce other colors). Both blue and violet lasers can also be constructed using frequency-doubling of infrared laser wavelengths from diode lasers or diode-pumped solid-state lasers.

Diode lasers which emit light at 445 nm are becoming popular as handheld lasers. Lasers emitting wavelengths below 445 nm appear violet (but are sometimes called blue lasers). Some of the most commercially common blue lasers are the diode lasers used in Blu-ray applications which emit 405 nm "violet" light, which is a short enough wavelength to cause fluorescence in some chemicals, in the same way as radiation further into the ultraviolet ("black light") does. Light of a shorter wavelength than 400 nm is classified as ultraviolet.

Devices that employ blue laser light have applications in many areas ranging from optoelectronic data storage at high density to medical applications.

International Conference on Nitride Semiconductors

The International Conference on Nitride Semiconductors (ICNS) is a major academic conference and exhibition in the field of group III nitride research. It has been held biennially since 1995. Since the second conference in 1997, hosting of the event has rotated between the Asian, European and North American continents. The ICNS and the International Workshop on Nitride Semiconductors (IWN) are held in alternating years, both covering similar subject areas.

ICNS-9 was held at the Scottish Exhibition and Conference Centre in Glasgow, Scotland, on 10–15 July 2011. Keynote speakers included Professor Umesh Mishra (University of California Santa Barbara and Transphorm) and Professor Hiroshi Amano (Meijo University,

Nagoya). ICNS-10 was held in Washington, D.C., United States on 25–30 August 2013, ICNS-11 was held in Beijing, China 30 August–4 September 2015 and ICNS-12 will take place in Strasbourg, France on 24–28 July 2017.

International Electron Devices Meeting

The IEEE International Electron Devices Meeting (IEDM) is an annual micro- and nanoelectronics conference held each December that serves as a forum for reporting technological breakthroughs in the areas of semiconductor and related device technologies, design, manufacturing, physics, modeling and circuit-device interaction.The IEDM is where "Moore’s Law" got its name, as Gordon Moore first published his predictions in an article in Electronics Magazine in 1965. Ten years later he refined them in a talk at the IEDM, and from that point on people began referring to them as Moore's Law. Moore’s Law states that the complexity of integrated circuits would double approximately every two years.IEDM brings together managers, engineers, and scientists from industry, academia, and government around the world to discuss nanometer-scale CMOS transistor technology, advanced memory, displays, sensors, MEMS devices, novel quantum and nanoscale devices using emerging phenomena, optoelectronics, power, energy harvesting, and ultra-high-speed devices, as well as process technology and device modeling and simulation. The conference also encompasses discussions and presentations on devices in silicon, compound and organic semiconductors, and emerging material systems. In addition to technical paper presentations, IEDM includes multiple plenary presentations, panel sessions, tutorials, short courses, and invited talks and an entrepreneurship panel session conducted by experts in the field from around the globe.

The 64th annual IEDM will be held at the Hilton San Francisco Union Square hotel December 1–5, 2018.

International Workshop on Nitride Semiconductors

The International Workshop on Nitride Semiconductors (IWN) is a biennial academic conference in the field of group III nitride research. The IWN and the International Conference on Nitride Semiconductors (ICNS) are held in alternating years and cover similar subject areas. IWN is pioneered by Isamu Akasaki (Nagoya University, Meijo University) and Hiroshi Amano (Nagoya University), who are Nobel laureates in physics (2014)

- IWN2018 was held 11-16 November 2018 in Kanazawa, Japan, and chaired by Hiroshi Fujioka (the University of Tokyo, Japan)- IWN2016 was held 2-7 October 2016 in Orland, United States, and chaired by Tomas Palacios (Massachusetts Institute of Technology, USA)- IWN2012 was held 14–19 October 2012 in Sapporo, Japan and chaired by Hiroshi Amano (Nagoya University, Japan).

Isamu Akasaki

Isamu Akasaki (赤崎 勇, Akasaki Isamu, born January 30, 1929) is a Japanese physicist, specializing in the field of semiconductor technology and Nobel Prize laureate, best known for inventing the bright gallium nitride (GaN) p-n junction blue LED in 1989 and subsequently the high-brightness GaN blue LED as well.For this and other achievements, Akasaki was awarded the Kyoto Prize in Advanced Technology in 2009, and the IEEE Edison Medal in 2011. He was also awarded the 2014 Nobel prize in Physics, together with Hiroshi Amano and Shuji Nakamura, "for the invention of efficient blue light-emitting diodes, which has enabled bright and energy-saving white light sources".

John O'Keefe (neuroscientist)

John O'Keefe, (born November 18, 1939) is an American-British neuroscientist and a professor at the Sainsbury Wellcome Centre for Neural Circuits and Behaviour and the Research Department of Cell and Developmental Biology at University College London. He discovered place cells in the hippocampus, and that they show a specific kind of temporal coding in the form of theta phase precession. In 2014 he received the Kavli Prize in Neuroscience "for the discovery of specialized brain networks for memory and cognition", together with Brenda Milner and Marcus Raichle. He shared the Nobel Prize in Physiology or Medicine also that year, together with May-Britt Moser and Edvard Moser.

Light-emitting diode

A light-emitting diode (LED) is a semiconductor light source that emits light when current flows through it. Electrons in the semiconductor recombine with electron holes, releasing energy in the form of photons. This effect is called electroluminescence. The color of the light (corresponding to the energy of the photons) is determined by the energy required for electrons to cross the band gap of the semiconductor. White light is obtained by using multiple semiconductors or a layer of light-emitting phosphor on the semiconductor device.Appearing as practical electronic components in 1962, the earliest LEDs emitted low-intensity infrared light. Infrared LEDs are used in remote-control circuits, such as those used with a wide variety of consumer electronics. The first visible-light LEDs were of low intensity and limited to red. Modern LEDs are available across the visible, ultraviolet, and infrared wavelengths, with high light output.

Early LEDs were often used as indicator lamps, replacing small incandescent bulbs, and in seven-segment displays. Recent developments have produced white-light LEDs suitable for room lighting. LEDs have led to new displays and sensors, while their high switching rates are useful in advanced communications technology.

LEDs have many advantages over incandescent light sources, including lower energy consumption, longer lifetime, improved physical robustness, smaller size, and faster switching. Light-emitting diodes are used in applications as diverse as aviation lighting, automotive headlamps, advertising, general lighting, traffic signals, camera flashes, lighted wallpaper and medical devices.Unlike a laser, the color of light emitted from an LED is neither coherent nor monochromatic, but the spectrum is narrow with respect to human vision, and functionally monochromatic.
