This joint development now provides the opportunity to leading High Brightness HBLED and Laser Diode developers to increase optical efficiency significantly compared with structures grown on conventional c-plane GaN substrates. With TDI's HVPE technology the semi-polar GaN can be utilized in high brightness LEDs, laser diodes, and high electron mobility transistors (HEMTs).
