In order to improve the performance of power electronic and photo-passive devices, it is important to evaluate the in-gap states in III-V nitrides and to reduce them. We have developed the apparatus of photothermal deflection spectroscopy (PDS) for evaluating III-V nitride materials. Not only tail states above the valence band, but also the deeper levels in the band gap can be detected by PDS. Advantages of PDS technique are to detect Urbach energy and defect levels for electrically and optically inactive sample with 1) no electrode, 2) coverage of deeper levels, and 3) detection of all charge states. In this study, the PDS data for InGaN alloy films and Mg ion implanted GaN will be presented. |
