Machine learning analysis of structural data to predict electronic properties in near-surface InAs quantum wells
Patrick J. Strohbeen, Abtin Abbaspour, Amara Keita +12
Semiconductor crosshatch patterns in thin film heterostructures form as a result of strain relaxation processes and dislocation pile-ups during growth of lattice mismatched materia…
Kerr nonlinearity and parametric amplification with an Al-InAs superconductor-semiconductor Josephson junction
Z. Hao, T. Shaw, M. Hatefipour +5
Nearly quantum limited Josephson parametric amplifiers (JPAs) are essential components in superconducting quantum circuits. However, higher order nonlinearities of the Josephson co…
Andreev reflection of quantum Hall states through a quantum point contact
Mehdi Hatefipour, Joseph J. Cuozzo, Ido Levy +4
We investigate the interplay between the quantum Hall (QH) effect and superconductivity in InAs surface quantum well (SQW)/NbTiN heterostructures using a quantum point contact (QPC…
Characterizing losses in InAs two-dimensional electron gas-based gatemon qubits
William M. Strickland, Lukas J. Baker, Jaewoo Lee +9
The tunnelling of cooper pairs across a Josephson junction (JJ) allow for the nonlinear inductance necessary to construct superconducting qubits, amplifiers, and various other quan…
The study of contact properties in edge-contacted graphene-aluminum Josephson junctions
Zhujun Huang, Neda Lotfizadeh, Bassel H. Elfeky +8
Transparent contact interfaces in superconductor-graphene hybrid systems are critical for realizing superconducting quantum applications. Here, we examine the effect of the edge-co…
Magneto-anisotropic weak antilocalization in near-surface quantum wells
S. M. Farzaneh, Mehdi Hatefipour, William F. Schiela +6
We investigate the effects of an in-plane magnetic field on the weak antilocalization signature of near-surface quantum wells lacking bulk and inversion symmetry. The measured magn…
