Self-Consistent Model for Gate Control of Narrow-, Broken-, and Inverted-Gap (Topological) Heterostructures
Maximilian Hofer, Christopher Fuchs, Moritz Siebert +8
Even small electrostatic potentials can dramatically influence the band structure of narrow-, broken-, and inverted-gap materials. A quantitative understanding often necessitates a…
Phase-dependent supercurrent and microwave dissipation of HgTe quantum well Josephson junctions
Wei Liu, Stanislau U. Piatrusha, Lena Fürst +4
We measured the microwave response of a HgTe quantum well Josephson junction embedded into an RF SQUID loop which is inductively coupled to a superconducting resonator. The side-co…
Highly efficient broadband THz upconversion with Dirac materials
Tatiana A. Uaman Svetikova, Igor Ilyakov, Alexey Ponomaryov +16
The use of the THz frequency domain in future network generations offers an unparalleled level of capacity, which can enhance innovative applications in wireless communication, ana…
Period-doubling in the phase dynamics of a shunted HgTe quantum well Josephson junction
Wei Liu, Stanislau U. Piatrusha, Xianhu Liang +7
The fractional AC Josephson effect is a discerning property of topological superconductivity in hybrid Josephson junctions. Recent experimental observations of missing odd Shapiro…
Overlapping Top Gate Electrodes based on Low Temperature Atomic Layer Deposition for Nanoscale Ambipolar Lateral Junctions
Christopher Fuchs, Lena Fürst, Hartmut Buhmann +2
We present overlapping top gate electrodes for the formation of gate defined lateral junctions in semiconducting layers as an alternative to the back gate/top gate combination and…
Topological band inversion in HgTe(001): surface and bulk signatures from photoemission
Raphael C. Vidal, Giovanni Marini, Lukas Lunczer +14
HgTe is a versatile topological material and has enabled the realization of a variety of topological states, including two- and three-dimensional (3D) topological insulators and to…
