| Research Abstract |
On the study, InGaNof the key material for Energy-saving society could be grown using a new growth system, where high quality growth of InGaN and high growth rate were realized.
The wavelength emitted from InGaN can be varied from 365nm to 1900nm by controlling the solid In composition in InGaN alloy. Therefore, InGaN has attracted attention as a high-efficiency LED, LD and solar cell. However, it is difficult to grow InGaN of In >20%. There is no example of successful high quality InGaN. It was found that InGaN ofIn > 20% could be grown by a new growth system.
