Dr. Srinivas Gandrothula's article: Slashing the cost of semi-polar substrates

Dr. Srinivas  Gandrothula's article appeared in a research review of the latest issue Compound Semiconductor magazine.

Slashing the cost of semi-polar substrates: freeing films created by lateral layer overgrown yields small semi-polar substrates

Volume 26 Issue 4  page 51

 

Team spokesman Srinivas Gandrothula told Compound Semiconductor that he and his co-workers have been working on this project for more than three years, with efforts directed at producing both semi-polar and non-polarbars. Success with the later led to a claim for the first functional, thin-film, edge-emitting laser, reported in 2019. As it is not possible to grow high-quality indium-rich epilayers on non-polar planes, the work recently diversified to include the fabrication of semi-polar bars.
