Biography
David Cherns is Professor in Department of Physics University of Bristol, United Kingdom
Research Interest
His interests lie in the application of novel electron microscopy techniques to the analysis of defects and interfaces, particularly in semiconductors, to clarify microstructure/property relationships. His present research includes the development of new materials for field emission displays and solar cells, and studies of the role of defects in GaN light-emitting structures. In the latter, we have used transmission electron microscopy to analyse threading defects including dislocations, nanopipes and inversion domains
