Distributed Current Injection into a One-Dimensional Ballistic Edge Channel
Kristof Moors, Christian Wagner, Helmut Soltner +3
We generalize Landauer's theory of ballistic transport in a one-dimensional (1D) conductor to situations where charge carrier injection and extraction are not any more confined to…
How cold is the junction of a millikelvin scanning tunnelling microscope?
Taner Esat, Xiaosheng Yang, Farhad Mustafayev +3
We employ a scanning tunnelling microscope (STM) cooled to millikelvin temperatures by an adiabatic demagnetization refrigerator (ADR) to perform scanning tunnelling spectroscopy (…
Probing edge state conductance in ultra-thin topological insulator films
Arthur Leis, Michael Schleenvoigt, Kristof Moors +8
Quantum spin Hall (QSH) insulators have unique electronic properties, comprising a band gap in their two-dimensional interior and one-dimensional spin-polarized edge states in whic…
Surface Conductivity of Si(100) and Ge(100) Surfaces Determined from Four-Point Transport Measurements Using an Analytical N-Layer Conductance Model
Sven Just, Helmut Soltner, Stefan Korte +2
An analytical N-layer model for charge transport close to a surface is derived from the solution of Poisson's equation and used to describe distance-dependent electrical four-point…
Surface and Step Conductivities on Si(111) Surfaces
Sven Just, Marcus Blab, Stefan Korte +3
Four-point measurements using a multi-tip scanning tunneling microscope (STM) are carried out in order to determine surface and step conductivities on Si(111) surfaces. In a first…
