Superfluid response of an atomically thin, gate-tuned van der Waals superconductor
Alexander Jarjour, G. M. Ferguson, Brian T. Schaefer +4
A growing number of two-dimensional superconductors are being discovered in the family of layered van der Waals (vdW) materials. Due to small sample volume, their characterization…
Electrically tunable and reversible magnetoelectric coupling in strained bilayer graphene
Brian T. Schaefer, Katja C. Nowack
The valleys in hexagonal two-dimensional systems with broken inversion symmetry carry an intrinsic orbital magnetic moment. Despite this, such systems possess zero net magnetizatio…
Scanning SQUID microscopy in a cryogen-free dilution refrigerator
D. Low, G. M. Ferguson, Alexander Jarjour +4
We report a scanning superconducting quantum interference device (SQUID) microscope in a cryogen-free dilution refrigerator with a base temperature at the sample stage of at least…
Gate-Tunable Graphene Hall Sensors with High Magnetic Field Sensitivity
Brian T. Schaefer, Lei Wang, Alexander Jarjour +4
Solid-state magnetic field sensors are important to both modern electronics and fundamental materials science. Many types of these sensors maintain high sensitivity only in a limit…
Evolution of superconductivity in ultrathin NbS2
Rusen Yan, Guru Khalsa, Brian T. Schaefer +5
We report a systematic study of thickness-dependent superconductivity and carrier transport properties in exfoliated layered 2H-NbS2. Hall-effect measurements reveal 2H-NbS2 in its…
