• Making reliable electrical contacts to
  semiconducting materials is crucial for
  electronic device performance. Over the past
  decades, significant research efforts have been
  devoted to the fundamental understanding of
  metal/semiconductor interfaces in traditional
  materials. As new materials such as nanotubes,
  nanowires and molecules are being explored for
  nanoelectronics, many of the concepts developed
  for bulk contacts need to be re-examined because
  of the much different physics at the nanoscale.
  In this talk, I will discuss theoretical work
  addressing the basic properties of contacts to
  nanostructures. The factors determining the band
  alignment at the interface, including the role of
  Fermi level pinning will be addressed.
