On-chip control of twist angle in 2D materials
Researchers developed a microelectromechanical system (MEMS) device that allows voltage-controlled manipulation of the twist angle and interlayer separation between two sheets of 2D material. This enables tuning of interfacial properties like moiré patterns and circular dichroism. Potential applications include tunable classical and quantum light sources.
