Probing embedded topological modes in bulk-like GeTe-SbTe heterostructures

Hisao Nakamura, Johannes Hofmann, Nobuki Inoue +5

The interface between topological and normal insulators hosts metallic states that appear due to the change in band topology. While these topological states at a surface, i.e., a t…

Thermally activated diffusion and lattice relaxation in (Si)GeSn materials

Nils von den Driesch, Stephan Wirths, Rene Troitsch +5

Germanium-Tin (GeSn) alloys have emerged as a promising material for future optoelectronics, energy harvesting and nanoelectronics owing to their direct bandgap and compatibility w…

Capacitance-voltage measurements of (BiSb)Te field effect device

Jimin Wang, Markus Schitko, Gregor Mussler +2

Capacitance-voltage () traces in n-type-(BiSb)Te/oxide/metal capacitor structures using an AC capacitance bridge are investigated. By tuning the t…

Phase-coherent loops in selectively-grown topological insulator nanoribbons

Jonas Kölzer, Daniel Rosenbach, Christian Weyrich +9

Universal conductance fluctuations and the weak antilocalization effect are defect structure specific fingerprints in the magnetoconductance that are caused by electron interferenc…

Long-lived non-equilibrium superconductivity in a non-centrosymmetric Rashba semiconductor

V. Narayan, P. C. Verpoort, J. R. A. Dann +8

We report non-equilibrium magnetodynamics in the Rashba-superconductor GeTe, which lacks inversion symmetry in the bulk. We find that at low temperature the system exhibits a non-e…
