摘要：

The linear electro-optic (Pockels) effect for hexagonal GaN was studied by electrolytic electroreflectance spectroscopy. The electric Field strength and space charge region parameters were extracted from Franz-Keldysh oscillations and photocurrent spectra. Data analysis yielded for the linear electro-optic coefficient r(13) a value of (1.55 +/- 0.08) pm V-1 indicating an appreciable ionic contribution which can be related to the converse piezoelectric effect.
