SUMMARY:The Superconductivity of Topologically Protected Surface State
 s\, R. G. Herb Condensed Matter Seminar\, Nicholas Sedlmayr\, Michigan
  State University
DESCRIPTION:When a superconductor and a normal material are brought to
 gether there is a proximity effect where the normal material takes on 
 some superconducting properties near the interface. Similarly the topo
 logically protected surface states recently found on the surfaces of s
 pecial crystals can leak into appropriate adjoining materials. We brin
 g these two effects into proximity and study how superconductivity and
  topologically protected surface states interact with each other\, a s
 ituation of interest in the search for Majorana bound states. We look 
 at the scanning tunneling microscopy of a large topological insulator 
 with superconducting islands deposited on the surface\, and analyze re
 levant theoretical models. The density of states of both the topologic
 al insulator and the superconductor turn out to exhibit interesting pr
 oximity effects.
