Field effect two-dimensional electron gases in modulation-doped InSb surface quantum wells
E. Annelise Bergeron, F. Sfigakis, Y. Shi +6
We report on transport characteristics of field effect two-dimensional electron gases (2DEG) in surface indium antimonide quantum wells. The topmost 5 nm of the 30 nm wide quantum…
Solution to the Gliding Tone Problem
Brian Cowan, Andrew Morris-Costigliola, George Nichols
The solution is given to the classical problem of an oscillator driven by a sinusoid of steadily-varying frequency. A closed analytical expression is obtained in the case where the…
Evolution of interlayer and intralayer magnetism in three atomically thin chromium trihalides
Hyun Ho Kim, Bowen Yang, Siwen Li +16
We conduct a comprehensive study of three different magnetic semiconductors, CrI, CrBr, and CrCl, by incorporating both few- and bi-layer samples in van der Waals tunne…
Origin of magnetoresistance suppression in thin -MoTe
Shazhou Zhong, Archana Tiwari, George Nichols +4
We use both classical magnetotransport and quantum oscillation measurements to study the thickness evolution of the extremely large magnetoresistance (XMR) material and type-II Wey…
Magnetic Field Dependent Microwave Losses in Superconducting Niobium Microstrip Resonators
Sangil Kwon, Anita Fadavi Roudsari, Olaf W. B. Benningshof +8
We describe an experimental protocol to characterize magnetic field dependent microwave losses in superconducting niobium microstrip resonators. Our approach provides a unified vie…
Frequency Dependence of the Supersolid Signature in Polycrystalline 4He
George Nichols, Malcolm Poole, Jan Nyeki +2
We report studies, using a two mode torsional oscillator, of the putative supersolid signature in polycrystalline 4He. Measurements at two frequencies enable us to eliminate the vi…
