Columbia Engineering researchers report that they have demonstrated a nearly ideal transistor made from a 2D material stack – with only a two-atom-thick semiconducting layer – by developing a completely clean and damage-free fabrication process. Their method shows vastly improved performance compared to 2D semiconductors fabricated with a conventional process, and could provide a scalable platform for creating ultra-clean devices in the future.

These ionic materials exhibit optical properties not found in 2D covalent semiconductors eg graphene, making them promising alternatives to silicon for future electronic devices. To the growing list of 2D semiconductors, eg graphene, boron nitride, and molybdenum disulfide, whose unique electronic properties make them potential successors to silicon in future devices, you can now add hybrid organic-inorganic perovskites...
