The electronic structure and properties of semiconductor | |
interfaces including both vacuum-semiconductor and metal- | |
semiconductor interfaces as well as relevant metal and | |
semiconductor materials have been investigated under this | |
contract. The emphasis has been on elucidating the | |
electronic properties of these materials and their | |
interfaces, e.g., metal-semiconductor Schottky barriers, | |
which are of far reaching importance in such | |
semiconductor devices as MOSFETS, CCD devices, | |
photovoltaic devices, etc. Extensive studies of the | |
electronic structure of semiconductor surfaces and | |
interfaces and related metal surfaces have been performed | |
as a function of surface preparation (include laser | |
annealing), doping, thickness of adsorbed overlayers, | |
etc. The principle technique used has been photoelectron | |
spectroscopy (XPS and UPS - with an emphasis on angle- | |
resolved studies using synchrotron radiation and yield | |
spectroscopy); other techniques include electron energy | |
loss spectroscopy, low energy electron diffraction and | |
theoretical band structure methods. Major achievements of | |
our research program includes world-leading contributions | |
to: (1) the electronic structure of cleaned and annealed | |
Si(111) surfaces; (2) accurate experimental | |
determinations of electron energy vs momentum band | |
dispersions E(k) of selected materials (such E(K) | |
dispersions are of central importance in solid state | |
physics in understanding the electronic, physical and | |
chemical properties of materials); and (3) the | |
development and application of surface core level | |
spectroscopy, a promising new photoemission technique. | |
