Stacking two-dimensional van der Waals (vdW) materials rotated with respect to each other
show versatility for studying exotic quantum phenomena. In particular, anisotropic layered …

Neutral and charged excitons (trions) in atomically thin materials offer important capabilities
for photonics, from ultrafast photodetectors to highly efficient light-emitting diodes and lasers …

Quantum devices, which rely on quantum mechanical effects for their operation, may offer
advantages, such as reduced dimensions, increased speed, and energy efficiency …

Thin transition metal dichalcogenides sustain superconductivity at large in-plane magnetic
fields due to Ising spin-orbit protection, which locks their spins in an out-of-plane orientation …

We demonstrate that Andreev modes that propagate along a transparent Josephson
junction have a perfect transmission at the point where three junctions meet. The chirality …

Thin NbSe2 retains superconductivity at a high in-plane magnetic field up to 30 T. In this
work we construct a novel atomically thin, all van der Waals SQUID, in which current flows …

Heterostructures between two-dimensional quantum spin Hall insulators (QSHIs) and
superconducting materials can allow for the presence of Majorana fermions at their …

van der Waals Josephson junctions utilize the interface between two superconducting NbSe
2 crystal flakes as a tunnel barrier. We fabricate such junctions by a dry-transfer procedure …

In this doctoral thesis, we developed a novel method to equip a two-dimensional layer of the
semiconductor molybdenum disulfide with superconducting contacts for the first time. For …

A Josephson junction device includes a planar arrangement including a first two-
dimensional (2D) material layer, a graphene layer, and a second 2D material layer planarly …
