Saphlux introduced semi polar gallium nitride material, creating a brighter LED possible

With the first generation of C GaN based solid state lighting materials bottleneck, semipolar Gan materials become a hot research topic in optical materials around the world, but has been unable to solve the problem of mass production, high price. Founded in 2014, the start-up company Saphlux, has developed a new technology, can be directly on the standard large size sapphire substrate to grow semi polar gallium nitride, to solve the problem of mass production.

Popular, Saphlux technology can make a very bright LED". This sounds very simple, but it is difficult to achieve. In the LED field, the polarization effect of the first generation of Gan solid lighting materials will lead to the inherent brightness of LED chip is always low, resulting in a large number of chip corresponding terminal products need, and can not meet the demand of high power applications. And a new generation of semipolar Gan materials in theory achieve large power single chip LED, the industry has pointed out a new road, but has been unable to solve the problem of mass production.

In the traditional growth mode, semi polar materials can only be achieved through oblique block type (GaN on sapphire growth needs). This way of production can not be achieved, a small piece of semi polar gallium nitride material prices are very expensive (up to $2000), can only be used for scientific research, not commercial. Nobel, who has studied the polarity of gallium nitride material, has been doing research in this field in the past, but has not been successful in the past, but has not been successful in the study of this kind of material in the past years, but the results of this research have been made in the past. However, the research has been carried out in.

Therefore, in order to mass production of semi polar gallium nitride material, the core is to find a new way to control its growth on sapphire. Saphlux established in 2014 through several tests at the beginning of this year, finally found a solution (involving commercial secrets like inconvenient disclosed), breaking the original semi polar GaN growth pattern, large size sapphire substrate can not only in the standard directly grown on semipolar Gan, can directly control the shape and direction of growth crystal.

This means that the underlying technology breakthrough, is expected to break down the first generation of materials and green light quantum efficiency bottleneck, made of LED and the next generation of high power laser products, high luminous efficiency, especially for major medical and outdoor lighting requirements for the field of high significance. Therefore, just announced the success of the research, Saphlux has received a lot of orders, including four of the world's top 10 LED vendors, apple mLED display of a supplier and a well-known American MR Hard Suits Inc.

Saphlux technology and modern production line completely match, the basic use of the original material can be produced in accordance with the original process. Saphlux founder Chen Chen told 36 krypton, the team has just purchased a R & D production equipment, by the end of the year to meet the needs of existing customer research and development. Plans to expand production capacity in mid next year, by the end of 17 to achieve mass production.

Although scholars now have people doing research in this area, but Chen Chen said, Saphlux is the only commercially available a master production of high quality semi polar materials company, has now entered the commercial products, while also actively layout patents, technical barriers will have at least 3-5 years.

Saphlux was founded in 2014 by Professor Han Zhong and Dr. Chen Chen in the United states. Among them, Professor Han has led his painstaking research team Gan, after six and a half years of efforts, successfully made the world's first large-scale semi polar gallium nitride. Now the team has a total of 5 core members, one of South Korea's researchers have also learned from Nakamura Shuji.

Saphlux was founded at the beginning of the real, LIAN, PreAngel and Yale VC $1 million 800 thousand financing, and set up a branch in Nanjing. The company plans to the end of the month to open a new round of financing, mainly used to strengthen research and development, expand the customer, at the end of next year, the amount of.
