Tungsten-Doped Vanadium Dioxide Films Advance Optoelectronic Devices 67

The metal-insulator transition (MIT) property of vanadium dioxide (VO?) makes it a crucial functional layer for numerous optoelectronic devices. However, its growth temperature requirement (450°C) and MIT temperature requirement (60°C) limit its compatibility in optoelectronic devices, especially in flexible substrate applications. Researchers from Beijing University of Technology and Tsinghua University have discovered a layer-by-layer transfer method of wafer-scale tungsten-doped vanadium dioxide films (W-VO? films), enabling low MIT temperatures (down to 40°C) and quasi-gradient doping integration. This advancement pushes the application…
