Thermoelectric imaging of structural disorder in epitaxial graphene
Sanghee Cho, Stephen Dongmin Kang, Wondong Kim +9
Heat is a familiar form of energy transported from a hot side to a colder side of an object, but not a notion associated with microscopic measurements of electronic properties. A t…
Electric Field Tuning of the Surface Band Structure of Topological Insulator Sb2Te3 Thin Films
Tong Zhang, Jeonghoon Ha, Niv Levy +2
We measured the response of the surface state spectrum of epitaxial Sb2Te3 thin films to applied gate electric fields by low temperature scanning tunneling microscopy. The gate dep…
Scanning Tunneling Microscopy of Gate Tunable Topological Insulator Bi2Se3 Thin Films
Tong Zhang, Niv Levy, Jeonghoon Ha +2
Electrical field control of the carrier density of topological insulators (TI) has greatly expanded the possible practical use of these materials. However, the combination of low t…
