Twisting 2D hBN layers unlocks unprecedented control of quantum light
Researchers demonstrated that rotating ultra‑thin hexagonal boron nitride sheets can reversibly shift the color and wavelength of embedded quantum emitters far beyond what traditional solid‑state hosts allow. By picking up, stacking, and twisting the layers, they achieved spectral tuning orders of magnitude larger, a breakthrough reported in Science Advances.
Nanotech Study Shows Targeted Reprogramming of Scar and Dermatitis Skin Microenvironments
