Induced superconductivity in the two-dimensional topological insulator phase of cadmium arsenide
Arman Rashidi, Robert Kealhofer, Alexander C. Lygo +2
Hybrid structures between conventional, s-wave superconductors and two-dimensional topological insulators (2D TIs) are a promising route to topological superconductivity. Here, we…
Anomalous superconducting diode effect in a polar superconductor
Robert Kealhofer, Hanbyeol Jeong, Arman Rashidi +2
A superconductor with broken time reversal and inversion symmetry may exhibit nonreciprocal charge transport, including a nonreciprocal critical current, also known as superconduct…
Competition between magnetic order and charge localization in NaIrO thin crystal devices
Josue Rodriguez, Gilbert Lopez, Samantha Crouch +15
Spin orbit assisted Mott insulators such as sodium iridate (NaIrO) have been an important subject of study in the recent years. In these materials, the interplay of electro…
Exchange biased Anomalous Hall Effect driven by frustration in a magnetic Kagome lattice
E. Lachman, N. Maksimovic, R. Kealhofer +3
Co3Sn2S2 is a ferromagnetic Weyl semimetal that has been the subject of intense scientific interest due to its large anomalous Hall effect. We show that the coupling of this materi…
Black Arsenic: A Layered Semiconductor with Extreme in-plane Anisotropy
Yabin Chen, Chaoyu Chen, Robert Kealhofer +18
Two-dimensional (2D) layered materials emerge in recent years as a new platform to host novel electronic, optical or excitonic physics and develop unprecedented nanoelectronic and…
Observation of two-dimensional Fermi surface and Dirac dispersion in YbMnSb
Robert Kealhofer, Sooyoung Jang, Sinéad M. Griffin +9
We present the crystal structure, electronic structure, and transport properties of the material YbMnSb, a candidate system for the investigation of Dirac physics in the presen…
