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…
Local Measurements of the Superconducting Pairing Symmetry in CuxBi2Se3
Niv Levy, Tong Zhang, Jeonghoon Ha +4
Topological superconductors represent a newly predicted phase of matter that is topologically distinct from conventional superconducting condensates of Cooper pairs. As a manifesta…
Reversible Photomechanical Switching of Individual Engineered Molecules at a Surface
Matthew J. Comstock, Niv Levy, Armen Kirakosian +8
We have observed reversible light-induced mechanical switching for a single organic molecule bound to a metal surface. Scanning tunneling microscopy (STM) was used to image the fea…
