HREELS Studies of Al Adsorption on Si(111).

摘要

The search for a better understanding of the metal-semiconductor interface is an on going theme in surface research. Many different techniques have been applied to study a variety of metal-semiconductor systems to further this understanding. It is significant when many techniques have been applied to the same interface, building up a complete picture of its physical properties, and providing a case study for theorists to test their models and calculation methods against. We report here the results of a high-resolution electron energy loss spectroscopy (HREELS) study at zero momentum transfer. This is the first part of a study that will map out the full phonon dispersion.
