On Teachers' day to pay tribute to these masters of the LED industry!

Teacher's day! Chinese has a long tradition of teacher enjoys a variety of honour the teacher and respect his teaching. ". Special mention is the teacher, the teacher's another title - master. As the saying goes, "a teacher for a day is a father for a lifetime". No matter in which industry, which enterprises, have the tradition of master apprentice, master is the past and promote the development of the industry.

On Teachers' day, let us pay tribute to the masters of light and illumination for their contribution to the cause of humanity.

A famous gaotu,

1 Nick ho Lun Yake & George Crawford

The two is mentoring. As a teacher, Nick Holonyak invented the first visible light emitting diode (LED) in 1962, which set off the second revolution in the history of lighting since the invention of the electric light bulb by Edison. Nick Holonyak is known as the father of LED". What's more, Nakamura Shuji's LD diode, which was promising a few days ago, was pioneered by Mr Nick Holonyak, who invented the first semiconductor laser device that emits red light.

As a student of George Crawford marching predecessors footsteps, invented in 1972 the first orange yellow light LED, its brightness is 10 times the previous red LED, which marks the first step toward improving the luminous efficiency of LED towards the direction. George Crawford is known as the father of LED". He also participated in the first large-scale commercial production of red LED. He developed the first high brightness yellow and red LED, and in decades to contribute to the development of efficient white LED.

2 days Ye Hao & Chiqiyong

The two is mentoring. Amano Hiroshi in 1983 graduated from the University of lucky to enter the laboratory of Akasaki Yong, to get a doctorate in 1989, followed by 7 years of Akasaki Yong. The two Nobel prize in physics in 2014.

1983, Akasaki Yong produced with silicon carbide, Zinc Oxide, gallium nitride and aluminum nitride four kinds of materials to do the sapphire substrate buffer layer idea. As a result of a very time-consuming attempt, he will be the first of the two materials of the experiment to the students and their colleagues in the past. However, after a period of hard work, we have failed to achieve the desired results. Akasaki Yong decided to try again with aluminum nitride, which naturally fell to his graduate student, Amano Hiroshi. Tian Hao day and night to do a period of time, the experiment was a success. Production of aluminum nitride buffer layer when the temperature is controlled at 400~500 degrees Celsius secret was Akasaki Yong two teachers and students mastered. After that, two students and their teachers in 1985 using gas phase epitaxial growth method successfully developed gallium nitride single crystal. Akasaki Yong and Amano Hiroshi et al in 1986 in the form of papers related to the research results.

Akasaki Yong deserves to be a teacher, will guide students career direction. In 1989, he directed another graduate student through the addition of magnesium, and then use a low speed electron beam irradiation, and finally made a gallium nitride P crystal. This breakthrough, but also caused a great sensation in the international arena. Later, the Akasaki Yong team and at the end of 1989 to done in one vigorous effort successfully developed the world's first Gan blue light-emitting diode PN junction.

Two, the world bright master

1 Thomas Alva Edison: father of lights

The inventor of the first electric light was not Edison, but the improvement of the electric light by Edison. In early 1801, a man named Humphry David, a British chemist in the laboratory with a platinum wire electric light; in 1810, he invented two electrified carbon occurs between the arc and the lighting of the "electric candle", this is the first prototype of the light. Another British Electrical Engineer Joseph Swan after nearly 30 years of research, in December 1878 made by carbon filament power vacuum bulb light.

The Swan bulb reports to Edison with great inspiration. In October 1879, Edison finally succeeds in making carbon fiber as the filament for the incandescent light bulb, called "carbonized cotton filament incandescent lamp", then a large number of production, and the establishment of the company set up power stations and the corresponding transmission network infrastructure, soon led lamps have been widely used in the United states. In the meantime, he continued to improve the technology, and ultimately determined to tungsten filament, known as the "tungsten lamp", and the use of stereotypes so far, Edison has become a recognized inventor of the electric light.

2 Albert Einstein: father of modern physics

Einstein is recognized as the greatest physicist since Galileo and Newton. He argued that the energy of light is not evenly distributed, but that it is dependent on the dispersion of photons, and that the energy of the photon is related to the frequency of the light. This breakthrough theory not only explains the photoelectric effect, but also promotes the birth of quantum mechanics.

3 Nakamura Shuji: father of Blu ray LED

Nakamura Shuji in 1993 in Japan Nichia Corporation (Nichia Corporation) during the inauguration, GaN developed a LED based high brightness blue, which is well known. At that time, the development of a blue LED is considered impossible, the previous 20 years only red and green LED. Nakamura Shuji's innovation allows LED manufacturers to produce three primary colors (red, green and blue) LED, which makes it possible to achieve 16 million color. Perhaps most importantly, the LED industry to use this new technology to start commercial production of white LED (semiconductor eco light). Nakamura Shuji won the 2014 Nobel prize in physics.
