Planar Tunneling and Andreev Bound State Spectroscopy of YBa2Cu3O7- d Thin Films Using Solution-Deposited Zirconia Insulators
Planar tunnel spectroscopic measurements are performed on YBa2Cu3O7-δ (YBCO) thin films at four different crystallographic orientations. Since tunneling is a highly surface-sensitive probe on YBCO, films have been optimized for high surface quality. To fabricate the tunneling insulator, a novel …

Planar Tunneling and Andreev Bound State Spectroscopy of Yttrium Barium Copper Oxide Thin Films Using Solution-Deposited Zirconia Insulators
In addition, we have fabricated tunnel junctions with three different counter-electrode deposition techniques. In doing so, various behaviors of the tunneling conductance and its dependence on magnetic field, temperature, and injected current as a function of these counter-electrode deposition …

Imaging topological superconductivity in UTe_2
… a new wave of interest in p-wave superconducting states as it offers the exciting prospect of measuring unusual surface electronic states, such as zero-energy Andreev bound states, and helical or chiral topological surface states. The latter state being a prerequisite for non-Abelian fermion …

Engineering superconductivity in ballistic semiconductor nanowires
… devices. While evidence for Majorana bound states in nanowires has been shown, many of these devices show behavior far from suitable for quantum control of Majorana modes. Two major experimental obstables must be overcome to realize robust Majorana nanowire devices. First, interfacial …

Superconducting tunneling spectroscopy of low-dimensional materials
Due to technological advances in bottom-up and top-down approaches in device fabrication, scientists have been able to construct devices that have dimensions on the orders of ones or tens of nanometers. Low-dimensional materials are of great interest due to the emergence of quantum effects and …
