Phys.org  October 10, 2022 Ultra-thin 2D materials are frequently grown by exposing a hot metal surface to a specific gas, which results in the gas decomposing on the metal and forming the desired 2D material. Due to the hot temperatures involved, it is difficult to monitor the growth of 2D materials during the several intermediate steps involved before the 2D material is completed. An international team of researchers (Austria, UK) utilized helium atom scattering to discover and control the growth of novel 2D h-BN nanoporous phases during the CVD process. They found that prior to the formation of h-BN from […]
