We study the coupled charge density wave (CDW) and insulator-to-metal transitions in the
2D quantum material 1T-TaS2. By applying in situ cryogenic 4D scanning transmission …

Crystal defects play an important role in the degradation and failure of semiconductor
materials and devices. Direct determination of band gap of defects is a critical step for …

We theoretically demonstrate that screw dislocation (SD), a 1D topological defect widely
present in semiconductors, exhibits ubiquitously a new form of spin-orbit coupling (SOC) …

A dislocation, just like a phonon, is a type of atomic lattice displacement but subject to an
extra topological constraint. However, unlike the phonon which has been quantized for …

We investigate the nature of the superconducting (SC) state in curved nanostructures with
Rashba spin-orbit coupling (RSOC). In bent nanostructures with inhomogeneous curvature …

Quantum materials have a fascinating tendency to manifest novel and unexpected electronic
states upon proper manipulation. Ideally, such manipulation should induce strong and …

We provide a comprehensive theoretical framework to study how crystal dislocations
influence the functional properties of materials, based on the idea of a quantized dislocation …

Local electronic properties of quasi-two-dimensional Pb (111) islands with screw
dislocations of different types on their surfaces were experimentally studied by means of low …

Hot spots in niobium superconducting radio-frequency (SRF) cavities are important sources
of heat dissipation. Tracking their physical origin is the key to controlling and improving SRF …
