Since the isolation of graphene, we have recognized a number of materials that kind atomically skinny sheets. Like graphene, some of these sheets are made of a single element; others kind from chemical compounds the place the atomic bonds naturally create a sheet-like structure. Many of these materials have distinct properties. While graphene is an superb conductor of electricity, a number of others are semiconductors. And it truly is possible to tune their properties further established on how you prepare the layers of a multi-sheet stack

Given. all these options, it shouldn’t shock any person that researchers have figured out how to make electronics out of these materials, together with flash. memory and the. smallest transistors ever made, by some measures. Most of these, however, are demonstrations of the ability to make the hardware—they’re not built-in into a useful machine. But a group of researchers has now demonstrated that it truly is possible to go past basic demonstrations by building a 900-pixel imaging sensor utilizing an atomically skinny material

Most photo sensors presently consist of commonplace silicon semiconductors, manufactured utilizing the ordinary complementary metal–oxide semiconductor (CMOS) processes. But it truly is possible to substitute the silicon with one other semiconductor. In this case, the researchers used molybdenum disulfide, an atomically skinny materials that has seen a lot of use in experimental devices
