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…
Edge transport in InAs and InAs/GaSb quantum wells
Susanne Mueller, Christopher Mittag, Thomas Tschirky +4
We investigate low-temperature transport through single InAs quantum wells and broken-gap InAs/GaSb double quantum wells. Non-local measurements in the regime beyond bulk pinch-off…
Lateral p-n Junction in an Inverted InAs/GaSb Double Quantum Well
Matija Karalic, Christopher Mittag, Thomas Tschirky +3
We present transport measurements on a lateral p-n junction in an inverted InAs/GaSb double quantum well at zero and nonzero perpendicular magnetic fields. At a zero magnetic field…
