Charge manipulation and imaging of the Mn acceptor state in GaAs by Cross-sectional Scanning Tunneling Microscopy
A. M. Yakunin, A. Yu. Silov, P. M. Koenraad +3
An individual Mn acceptor in GaAs is mapped by Cross-sectional Scanning Tunneling Microscopy (X-STM) at room temperature and a strongly anisotropic shape of the acceptor state is o…
Andreev reflection at high magnetic fields: Evidence for electron and hole transport in edge states
J. Eroms, D. Weiss, J. De Boeck +2
We have studied magnetotransport in arrays of niobium filled grooves in an InAs/AlGaSb heterostructure. The critical field of up to 2.6 T permits to enter the quantum Hall regime.…
Spatial structure of an individual Mn acceptor in GaAs
A. M. Yakunin, A. Yu. Silov, P. M. Koenraad +5
The wave function of a hole bound to an individual Mn acceptor in GaAs is spatially mapped by scanning tunneling microscopy at room temperature and an anisotropic, cross-like shape…
Imaging of the [Mn2+(3d5) + hole] complex in GaAs by Cross-sectional Scanning Tunneling Microscopy
A. M. Yakunin, A. Yu. Silov, P. M. Koenraad +3
We present results on the direct spatial mapping of the wave-function of a hole bound to a Mn acceptor in GaAs. To investigate individual Mn dopants at the atomic scale in both ion…
Commensurability effects in Andreev antidot billiards
J. Eroms, M. Tolkiehn, D. Weiss +3
An Andreev billiard was realized in an array of niobium filled antidots in a high-mobility InAs/AlGaSb heterostructure. Below the critical temperature T_C of the Nb dots we observe…
