🔍 Layered semiconductors are attracting growing interest for quantum technologies  such as photonics, sensing, and spin-based devices. So far, most research has focused on artificially engineered materials . In contrast, natural layered materials  - like talc - have been largely overlooked, even though they offer several important advantages. 🌿 Talc and related silicate materials have a wide, direct bandgap, very few optically active defects, and a low density of nuclear sp
