Recently there has been a great deal of interest in studying the surfaces of materials with topologically non-trivial electronic states. These states enable not only new physical effects, but provide a new tool to spintronics and quantum computation. Despite the intense experimental efforts to study these compounds, the origin of the suppression of charge transport from the surface states remains a mystery. Towards this end, I will discuss our groups efforts to better understand the surface state charge transport using optical spectropy. In addition I will detail a new method we have devised that enables us to produce high temperature superconductivity in a topological insulator via the proximity effect, which may lead to new routes for quantum computation.
