Most of the current methods for synthesis two-dimensional materials (2DMs) require temperatures not compatible with traditional back-end-of-line (BEOL) processes in semiconductor industry (450 °C). Here, we report a general BiOCl-assisted chemical vapor deposition (CVD) approach low-temperature 27 ultrathin 2DMs. In particular, by mixing BiOCl selected metal powders to produce volatile intermediates, show that 2DMs can be produced at 280-500 °C, which are ~200-300 °C lower than required...
