Abstract

A study of thermo-optical coefficient (dn/dT) of GaN using spectroscopic ellipsometry is made, and a large thermo-optical nonlinearity near band edge, which increases with increasing temperature, has been observed. Kramers-Kronig transformation has been used to verify our results and a qualitative consistency has been obtained.
