摘要

We investigated electric field modulated PL spectra of InGaN SQW in connection with the excitation light intensity dependence of PL spectra, and found clear evidence of a piezo electric field in the quantum well that is originated from lattice strain. From the sign of the electric field modulated PL signal, GaN polarity determined to be N face.
