CHANGE: Indium Selenide Takes on the Mantle of the New Wonder Material. “The semiconductor bit has always been the showstopper for graphene. Because it lacks a natural band gap, that property has to be engineered; but that takes away some of its attractive properties in terms of electron mobility. The form of indium selenide the Manchester researchers have developed has an inherent band gap, and thus requires no gerrymandering that might compromise its high electron mobility. In research published in the journal Nature Nanotechnology, the Manchester researchers found that the indium selenide had a room-temperature electron mobility of 2,000 square centimeters per Volt-second, which is significantly higher than that of silicon and even higher than few-layer dichalcogenides.”
