Abstract

Abstract The optical properties of hexagonal InN crystal are investigated by reflectance, absorption and photoluminescence method. With use of the theoretical formula of these spectra, both of conduction and valence band properties are analysed. As a result, the average effective electron and hole mass values at the band edge are found to be about 0.046(±0.01) m 0 and 0.2(±0.05) m 0 , respectively. The photoluminescence emitted from the cleaved edge was strongly polarized. The agreement of the peak energies of π and σ polarized light means that A, B, and C band edges are closely located in energy space. (© 2006 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
