Topological boundary states in engineered quantum-dot molecules on the InAs(111)A surface
Van Dong Pham, Yi Pan, Steven C. Erwin +3
Atom manipulation by scanning tunneling microscopy was used to construct quantum dots on the InAs(111)A surface. Each dot comprised six ionized indium adatoms. The positively charg…
Quantum dots on the InAs(110) cleavage surface created by atom manipulation
Van Dong Pham, Yi Pan, Steven C. Erwin +1
Cryogenic scanning tunneling microscopy was employed in combination with density-functional theory calculations to explore quantum dots made of In adatoms on the InAs(110) surface.…
Topological States in Dimerized Quantum-Dot Chains Created by Atom Manipulation
Van Dong Pham, Yi Pan, Steven C. Erwin +3
Topological electronic phases exist in a variety of naturally occurring materials but can also be created artificially. We used a cryogenic scanning tunneling microscope to create…
Acquisition and Analysis of Scanning Tunneling Spectroscopy Data WSe Monolayer
Randall M. Feenstra, Grayson R. Frazier, Yi Pan +5
Acquisition and analysis is described for scanning tunneling spectroscopy data acquired from a monolayer of WSe grown on epitaxial graphene on SiC. Curve fitting of the data is…
Quantum-Confined Electronic States arising from Moiré Pattern of MoS2-WSe2 Hetero-bilayers
Yi Pan, Stefan Fölsch, Yifan Nie +7
A two-dimensional (2D) hetero-bilayer system consisting of MoS2 on WSe2, deposited on epitaxial graphene, is studied by scanning tunneling microscopy and spectroscopy at temperatur…
Energy splitting of image states induced by the surface potential corrugation of InAs(111)A
J. Martínez-Blanco, S. C. Erwin, K. Kanisawa +1
By means of scanning tunneling spectroscopy (STS) we study the electronic structure of the III-V semiconductor surface InAs(111)A in the field emission regime (above the vacuum lev…
Light Emission from Ag(111) driven by Inelastic Tunneling in the Field Emission Regime
Jesús Martínez-Blanco, Stefan Fölsch
We study the light emission from a Ag(111) surface when the bias voltage on a scanning tunneling microscope (STM) junction is ramped into the field emission regime. Above the vacuu…
