Researchers manage to produce 2D MoSe2 sheets

Researchers from the SLAC lan in Stanford University developed a new method to make 2D material molybdenum diselenide or MoSe₂ that has possible applications in photoelectronic devices, such as light detectors and solar cells, and perhaps also novel electronic devices.

This is the first time single-layer MoSe₂ has been efficiently produced. The method they developed is based on molecular beam epitaxy, and starts with molybdenum and selenium, which are heated in a vacuum chamber until they evaporate. The two elements combined as a thin film. By tweaking the process, they managed to create thin films - one to eight atoms thick. Those sheets were grown on graphene substrates.
