Wafer-scale 2D magnetic films emerge thanks to a new low-defect growth technique

Phys · · 756 words · By Indian Institute

Researchers at the Indian Institute of Science (IISc) developed a novel Physical Vapor Transport Deposition (PVTD) technique to grow high-quality, wafer-scale two-dimensional magnetic materials (2D-MMs) using chromium chloride. This advancement overcomes previous limitations in material size and scalability, paving the way for integration into advanced electronics and spintronics. The process involved several key innovations, including substrate selection (synthetic mica) and controlled deposition conditions.
