Reserach Interests
Professor Dudley's research interests focus on crystal growth and characterization of defect structures in crystals with a view to determining their origins. The primary technique used is Synchrotron X-ray Topography which enables analysis of defects and generalized strain fields in single crystals in general, with particular emphasis on semiconductor, optoelectronic, and optical crystals, especially SiC, GaN, AlN, InP CdZnTe, HgCdTe, AlN, B12As2, ZnSe as well as proteins and other related materials. Establishing the relationship between crystal growth conditions and resulting defect distributions is a particular thrust area of interest to Dudley, as is the correlation between electronic/optoelectronic device performance and defect distribution. Also of interest is the understanding of the origins and extent of damage introduced during crystal surface preparation. In situ studies of defect formation during crystal growth and defect behavior during device processing and operation using synchrotron X-ray topography are also of interest. Other techniques routinely used in such analysis include Transmission Electron Microscopy, High Resolution Triple-Axis X-ray Diffraction, Atomic Force Microscopy, Scanning Electron Microscopy, Nomarski Optical Microscopy, Conventional Optical Microscopy, IR Microscopy and Fluorescent Laser Scanning Confocal Microscopy. Professor Dudley is the Director of the onsemi Research Center for Wide Bandgap Materials at Stony Brook University, where he pursues an integrated approach to enable fundamental understanding of the PVT growth process of SiC crystals through growth in conjunction with characterization and multimodal modeling.
