Abstract:

The technical program has continued to emphasize the fundamentals of optical techniques and electronic materials. The quantum statistics is examined for squeezed light and fractal noise. We continue to push the frontiers of coherent ultrashort-pulse spectroscopy by examining attosecond pulses in four- wave mixing experiments. Interfacial phenomena was studied in buried epitaxial insulator-semiconductor interfaces with laser photoemission and bimetal Schottky barriers on GaAs, respectively. Work on high pressure studies of II-VI superlattices has yielded information on stress and strain in these layered compounds. Direct infrared laser probing of chlorine atoms was implemented a technique of considerable general use in following Cl atom concentrations in etching environments. Finally, a new program in packaging science has been formulated for next years JSEP program.
