Carrier doping of BiSe surface by chemical adsorption -- a DFT study
Cheng Fan, Kazuyuki Sakamoto, Peter Krüger
BiSe is one of the most promising topological insulators, but it suffers from intrinsic n-doping due to Se-vacancies, which shifts the Fermi level into the bulk conduction…
Signature of spin-resolved quantum point contact in p-type trilayer WSe van der Waals heterostructure
K. Sakanashi, P. Krüger, K. Watanabe +5
In this study, the electrostatically induced quantum confinement structure, quantum point contact, has been realized in p-type trilayer tungsten diselenide-based van der Waals hete…
Ensemble averaged Madelung energies of finite volumes and surfaces
Peter Krüger
Exact expressions for ensemble averaged Madelung energies of finite volumes are derived. The extrapolation to the thermodynamic limit converges unconditionally and can be used as a…
Additively manufactured ultra-high vacuum chamber below mbar
N. Cooper, L. A. Coles, S. Everton +11
Metal-based additive manufacturing (AM) represents a paradigm change in engineering and production methods across multiple industries and sectors. AM methods enable mass reduction…
Atom chips with free-standing two-dimensional electron gases: advantages and challenges
G. A. Sinuco-Leon, Peter Krueger, T. M. Fromhold
In this work we consider the advantages and challenges of using free-standing two-dimensional electron gases (2DEG) as active components in atom chips for manipulating ultracold en…
Adsorption and STM imaging of tetracyanoethylene on Ag(001): An ab-initio study
Thorsten Deilmann, Peter Krüger, Michael Rohlfing +1
We investigate the adsorption of a single tetracyanoethylene (TCNE) molecule on the silver (001) surface. Adsorption structures, electronic properties, and scanning tunneling micro…
