Graphene thin films struggle to find an application

August 01, 2018 | Case Study

It is possible to grow a single atomic layer of graphene on a substrate, typically copper, via chemical vapor deposition. These films can then be transferred to other substrates by coating the graphene in the new substrate and etching away the copper. These graphene films offer outstanding electrical properties – electron mobility can be two to four times as high as that of crystalline silicon, and the films can be further doped to manipulate their properties. Startups, academics, and multinationals have sought to develop sensors, displays, and processors using graphene films.
