Organometallic topological insulators at interfaces

Topological insulators are materials with insulating bulk electronic states but conducting boundary states. Predicted as recently as 1987 and only experimentally observed in 2006, they present a new and rich playground in condensed matter physics holding promise for diverse applications. This masters project aims to be an exploratory phase of expanding this class of materials from inorganic films to two-dimensional organometallic sheet structures that have been theoretically predicted to bear topological insulators characteristics.
However, despite inherent advantages such as inexpensiveness, facile fabrication and mechanical flexibility experimental investigations are lacking. The aim of the present project is to develop bottom-up self-assembly protocols for the formation of two-dimensional organometallic compounds on suitable solid surfaces and subsequent mapping of their band structure. The fabrication will utilize ultra-high vacuum systems, whereas the initial atomic level structural characterization and probing of edge states will be performed with scanning tunneling microscopy and spectroscopy, respectively. For the most promising systems angular resolved photoelectron spectroscopy will be utilized for a detailed characterization of the band structure.
