A study of the elastic and electronic properties of III-nitride semiconductors
… based on the technologically important InxGa1_xN alloy system. An investigation of the effects of structural inhomogeneities in these systems is made; specifically, the impact of random alloy fluctuations and well width fluctuations on the electronic and optical properties is investigated. This …

A tight-binding analysis of the electronic properties of III-nitride semiconductors
… model to investigate the effect of local alloy fluctuations in bulk AlGaN alloys and InGaN quantum wells. We calculate the band gap evolution of Al1_xGaxN across the full composition range and compare it to experiment as well as fitting bowing parameters to the band gap as well as to the …

Cross-Sectional Scanning Tunneling Microscopy Investigations of Cleaved Iii-V Heterostructures
… and device sizes have reached the point where fluctuations on the atomic level may affect device performance. The need for a tool to characterize these structures has been satisfied by cross-sectional scanning tunneling microscopy (XSTM). This thesis details the development and application of …

Theory of carrier transport in III-Nitride based heterostructures
Wurtzite III-nitride materials and their alloys have attracted significant interest for solid state lighting applications. This is due to the direct band gaps of InN, GaN, and AlN crystals, which span a wide range of emission wavelengths. Due to the importance of these systems, the goal of …
