Resolving Few-Layer Antimonene/Graphene Heterostructures
Tushar Gupta, Kenan Elibol, Stefan Hummel +6
Two-dimensional (2D) antimony (Sb, antimonene) recently attracted interest due to its peculiar electronic properties and its suitability as anode material in next generation batter…
An atomic force microscope integrated with a helium ion microscope for correlative nanocharacterization
Santiago H. Andany, Gregor Hlawacek, Stefan Hummel +3
In this work, we report the integration of an atomic force microscope (AFM) into a helium ion microscope (HIM). The HIM is a powerful instrument, capable of sub-nanometer resolutio…
Scanning transmission electron microscopy under controlled low-pressure atmospheres
Gregor T. Leuthner, Stefan Hummel, Clemens Mangler +4
Transmission electron microscopy (TEM) is carried out in vacuum to minimize the interaction of the imaging electrons with gas molecules while passing through the microscope column.…
Efficient Bethe-Salpeter equations' treatment in dynamical mean-field theory
Agnese Tagliavini, Stefan Hummel, Nils Wentzell +3
We present here two alternative schemes designed to correct the high-frequency truncation errors in the numerical treatment of the Bethe-Salpeter equations. The schemes are applica…
Effective crystal field and Fermi surface topology: a comparison of d- and dp-orbital models
N. Parragh, G. Sangiovanni, P. Hansmann +3
The effective crystal field in multi-orbital correlated materials can be either enhanced or reduced by electronic correlations with crucial consequences for the topology of the Fer…
