Displacement-Field-Induced Ionization of Defect States in High-Quality hBN
Ilia Begichev, Daria Belotcerkovtceva, Iakov Reznikov +10
Encapsulation of two-dimensional (2D) materials with hexagonal boron nitride (hBN) is widely used to fabricate ultraclean van der Waals (vdW) heterostructures for optoelectronic an…
Polymer-free van der Waals assembly of 2D material heterostructures using muscovite crystals
Ian Babich, Timofey M. Savilov, Natalia A. Mamchik +14
The advent of van der Waals (vdW) heterostructures has enabled formation of bespoke materials with atomic precision, where numerous quantum and topological phenomena have already b…
Diode effect in Shapiro steps in an asymmetric SQUID with a superconducting nanobridge
Dmitrii S. Kalashnikov, Gleb S. Seleznev, Andrei Kudriashov +4
We investigate the Josephson diode effect in an asymmetric SQUID consisting of a sinusoidal Josephson junction formed by a BiTeSe flake and a superconducting Nb nanobridge…
Milli-Tesla Quantization enabled by Tuneable Coulomb Screening in Large-Angle Twisted Graphene
I. Babich, I. Reznikov, I. Begichev +15
The electronic quality of graphene has improved significantly over the past two decades, revealing novel phenomena. However, even state-of-the-art devices exhibit substantial spati…
Proximity screening greatly enhances electronic quality of graphene
Daniil Domaretskiy, Zefei Wu, Van Huy Nguyen +17
The electronic quality of two-dimensional systems is crucial when exploring quantum transport phenomena. In semiconductor heterostructures, decades of optimization have yielded rec…
Limitations of the current-phase relation measurements by an asymmetric dc-SQUID
Ian Babich, Andrei Kudriashov, Denis Baranov +1
Exotic quantum transport phenomena established in Josephson junctions (JJs) are reflected by a non-sinusoidal current-phase relation (CPR). The solidified approach to measure the C…
Revealing intrinsic superconductivity of the Nb/BiSbTeSe interface
Andrei Kudriashov, Ian Babich, Razmik A. Hovhannisyan +7
Typically, topological superconductivity is reachable via proximity effect by a direct deposition of superconductor (S) on top of a topological insulator (TI) surface. Here we obse…
