Strain Engineering a Charge Density Wave Phase in Transition Metal Dichalcogenide 1T-VSe
Duming Zhang, Jeonghoon Ha, Hongwoo Baek +10
We report a rectangular charge density wave (CDW) phase in strained 1T-VSe thin films synthesized by molecular beam epitaxy on c-sapphire substrates. The observed CDW structure…
Scanning Tunneling Spectroscopy of Proximity Superconductivity in Epitaxial Multilayer Graphene
Fabian D. Natterer, Jeonghoon Ha, Hongwoo Baek +5
We report on spatial measurements of the superconducting proximity effect in epitaxial graphene induced by a graphene-superconductor interface. Superconducting aluminum films were…
Creating Nanostructured Superconductors On Demand by Local Current Annealing
Hongwoo Baek, Jeonghoon Ha, Duming Zhang +10
Superconductivity results from a Bose condensate of Cooper-paired electrons with a macroscopic quantum wavefunction. Dramatic effects can occur when the region of the condensate is…
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…
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…
