Title
GaN-on-glass success.
Abstract
An interview with Jun Hee Choi of Samsung Advanced Institute of Technology is presented. When asked on the motivation behind his research, Jun Hee Choi reveals that the most important materials for making blue light emitting diodes (LEDs) is the growing gallium nitride (GaN). He says that the choice of materials for the pre-orienting layer is one of the difficulties in the GaN-based LEDs project. He adds that he is planning to improve the efficiency of GaN LEDs on a fused-silica glass.
