2D van der Waals magnetic/non-magnetic heterojunctions hold significant promise for spintronic devices. Achieving these functionalities hinges on the interfacial proximity effect, a critical factor.

Researchers used a nonlinear metasurface to experimentally demonstrate skyrmions that can be switched between electric and magnetic modes in free-space toroidal terahertz light pulses. WASHINGTON — ...

Monitoring trace gases with high sensitivity and selectivity is essential for environmental safety and smart monitoring systems. Recently, a research team led by Professor Baicheng Yao from Key ...

A major contribution of this work lies in enabling switchable selectivity through graphene doping engineering. Rather than altering the device structure, the researchers tuned the gas-sensing ...
