Chinese researchers develop 1,000 times faster process for wafer-scale 2D semiconductors

Chinese researchers have developed a process to grow wafer-scale two-dimensional semiconductors at about 1,000 times the previous speed, a report said. The team redesigned a chemical vapor deposition process and replaced a solid substrate with a liquid gold and tungsten bilayer to ease physical limits on growth speed. They produced a monolayer tungsten silicon nitride film and said the work suggests scalable manufacturing potential, though mass production, defects and cost remain obstacles.
