Quasiparticle scattering from topological crystalline insulator SnTe (001) surface states
Duming Zhang, Hongwoo Baek, Jeonghoon Ha +5
Recently, the topological classification of electronic states has been extended to a new class of matter known as topological crystalline insulators. Similar to topological insulat…
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…
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…
Power-Law Decay of Standing Waves on the Surface of Topological Insulators
Jing Wang, Wei Li, Peng Cheng +9
We propose a general theory on the standing waves (quasiparticle interference pattern) caused by the scattering of surface states off step edges in topological insulators, in which…
