Electron-Hole Interference in an Inverted-Band Semiconductor Bilayer
Matija Karalic, Antonio Štrkalj, Michele Masseroni +7
Electron optics in the solid state promises new functionality in electronics through the possibility of realizing micrometer-sized interferometers, lenses, collimators and beam spl…
Gate-tunable Electronic Transport in p-type GaSb Quantum Wells
Matija Karalic, Christopher Mittag, Michael Hug +6
We investigate two-dimensional hole transport in GaSb quantum wells at cryogenic temperatures using gate-tunable devices. Measurements probing the valence band structure of GaSb un…
Phase Slips and Parity Jumps in Quantum Oscillations of Inverted InAs/GaSb Quantum Wells
Matija Karalic, Christopher Mittag, Susanne Mueller +5
We present magnetotransport measurements of a strongly hybridized inverted InAs/GaSb double quantum well. We find that the spin-orbit interaction leads to an appreciable spin-split…
Edgeless and Purely Gate-Defined Nanostructures in InAs Quantum Wells
Christopher Mittag, Matija Karalic, Zijin Lei +4
Nanostructures in InAs quantum wells have so far remained outside of the scope of traditional microfabrication techniques based on etching. This is due to parasitic parallel conduc…
Observation of fractional quantum Hall effect in an InAs quantum well
Meng K. Ma, Md. Shafayat Hossain, K. A. Villegas Rosales +4
The two-dimensional electron system in an InAs quantum well has emerged as a prime candidate for hosting exotic quasi-particles with non-Abelian statistics such as Majorana fermion…
Passivation of Edge States in Etched InAs Sidewalls
Christopher Mittag, Matija Karalic, Susanne Müller +6
We investigate different methods of passivating sidewalls of wet etched InAs heterostructures in order to suppress inherent edge conduction that is presumed to occur due to band be…
