Abstract

The effects of free electron concentration were analyzed which ranged form 10 ¹⁷ to 10 ²⁰ cm ^-3. The optical absorption, Hall effect and ion mass spectrometry were used for performing the investigation. The intrinsic band gap of InN of about 0.7 to 1.7 eV was observed for optical absorption edge. The Burstein-Moss shift was used to account electron concentration dependence of optical absorption edge energy. The O and H impurities were not able to fully account for free electron concentration in films which was shown by secondary ion mass spectrometry.
