We investigate superconducting quantum interference devices consisting of two highly transmissive Josephson junctions coupled by a superconducting loop, all defined in an epitaxial InAs/Al heterostructure. A novel device design allows for independent

Wigner solids of wide quantum wells near Landau filling $\nu=1$

Autor: Ken W. West, Lloyd Engel, Loren Pfeiffer, Anthony Hatke, Yang Liu, Mansour Shayegan, Kirk Baldwin

Microwave spectroscopy within the Landau filling ($\ensuremath{\nu}$) range of the integer quantum Hall effect (IQHE) has revealed pinning mode resonances signifying Wigner solids (WSs) composed of quasiparticles or -holes. We study pinning modes of

High mobility InAs 2DEGs on GaSb substrates: a platform for mesoscopic quantum transport

Autor: Tai-Lung Wu, Aymeric Tuaz, Michael A. Capano, Candice Thomas, Michael J. Manfra, Tiantian Wang, Rosa E. Diaz, Ray Kallaher, Anthony Hatke, Geoffrey C. Gardner

High mobility, strong spin-orbit coupling, and large Land\'e g-factor make the two-dimensional electron gas (2DEG) in InAs quantum wells grown on nearly-lattice-matched GaSb substrates an attractive platform for mesoscopic quantum transport experimen

We report an experimental study of the scaling of zero-bias conductance peaks compatible with Majorana zero modes as a function of magnetic field, tunnel coupling, and temperature in one-dimensional structures fabricated from an epitaxial semiconduct

Mobility in excess of $10^{6}$ cm$^2$/Vs in InAs quantum wells grown on lattice mismatched InP substrates

Autor: Tian Wang, Michael J. Manfra, Anthony Hatke, Candice Thomas, Geoff Gardner

InAs-based two-dimensional electron systems grown on lattice mismatched InP substrates offer a robust platform for the pursuit of topologically protected quantum computing. We investigated strained composite quantum wells of In$_{0.75}$Ga$_{0.25}$As/
