Emergent photovoltage on SmB(6) surface upon bulk-gap evolution revealed by pump-and-probe photoemission spectroscopy
Recent studies suggest that an exemplary Kondo insulator SmB(6) belongs to a new class of topological insulators (TIs), in which non-trivial spin-polarized metallic states emerge on surface upon the formation of Kondo hybridization gap in the bulk. Remarkably, the bulk resistivity reaches more than...
