The emerging field of spintronics - in which an electron's spin rather than its charge is utilized - offers some spectacular advantages over traditional electronics, including high speed and low power processing. However, as a precursor to spintronic devices, a fundamental knowledge of spin-current sources and spin-transport is required. In this talk, graphene and topological insulator surfaces will be discussed as potential spintronic materials.
Graphene's spin transport properties have recently received much attention, however, in order for it to be useful in real devices, the production of patterned graphene using standard industrial processes is necessary. Our recent attempt to achieve this using solid state catalysts will be discussed.
Topological insulators (and related materials with strong spin-orbit coupling) are proposed to act as spin filters, yet a number of fundamental problems stand in its way. By engineering vicinal surfaces of such materials, 1-dimensional spin-separating surface states can be produced. The fundamental principals and practical challenges will be presented here.
