Summary
University of Technology Sydney researchers showed they can repeatedly lift, rotate and restack atom-thin hexagonal boron nitride to control embedded quantum light sources.
The twisting changed both the color and wavelength of emission, delivering a larger-than-expected shift and a more flexible tuning method than fixed-angle devices.
Because hBN is a layered 2D material, unlike bulk hosts such as diamond or silicon carbide, its sheets can be separated and reassembled to alter emitter behavior.
The Science Advances study points to more practical building blocks for quantum computing, secure communications and ultra-sensitive sensing, with potential uses in healthcare, cybersecurity and GPS.
