Skyrmion lattice order controlled by confinement geometry
Magnetic skyrmions forming two-dimensional (2D) lattices provide a versatile platform for investigating phase transitions predicted by Kosterlitz–Thouless–Halperin–Nelson–Young theory. While 2D meltin...
Photoexcitation-assisted EDMR on SiC JFETs for quantum sensing applications
Electrically detected magnetic resonance (EDMR) is a powerful tool to interrogate quantum phenomena in semiconductors, e.g., to facilitate microelectronic sensors such as magnetometers. However, effor...
Ferrovalleytricity in 2D multiferroic lattice with self-doped valley carriers
Realizing electrical control of the anomalous valley Hall effect (AVHE) and efficient generation of valley carriers are two fundamental challenges in valleytronics research. Here, we propose a ferroel...
Compact radio frequency module for gate-defined quantum dot qubits
Semiconductor quantum dot spin qubits, which employ radio frequency (RF) techniques for manipulation and readout, present a compelling pathway toward scalable quantum computation. We introduce a robus...
Exceptional piezoelectric performance originating from the development of distinct domains under AC electric field
Piezoelectric performance is closely linked to domain configuration evolution, and domain morphologies are significantly different under alternating current poling (ACP) and direct current poling (DCP...
