Chinese researchers have introduced a wafer-scale growth method for two-dimensional semiconductors, which significantly enhances production rates to 20 micrometres per minute, a 1,000-fold increase compared to traditional methods. This breakthrough addresses the critical lack of stable p-type materials necessary for pairing with n-type semiconductors, crucial for advanced transistor technologies.
The innovative approach utilizes a liquid gold-tungsten bilayer substrate and modifies the chemical vapour deposition process to achieve scalable growth of monolayer tungsten silicon nitride films. The material shows promising electrical, mechanical, and thermal properties, enabling its use in CMOS circuits and applications in optoelectronics and sensors. This development may lead to expanded capabilities in semiconductor manufacturing and commercialization of 2D technologies.
