Carbon Nanotubes (CNTs) have not yet met commercial expectations from a decade ago, and now hot on its heels is graphene. Graphene is considered a hot candidate for applications such as computers, displays, photovoltaics, and flexible electronics. IDTechEx market forecasts indicate that CNT and graphene transistors may be commercially available in volume from 2015 onwards, according to the new report \"Carbon Nanotubes and Graphene for Electronics Applications 2011-2021\". According to IDTechEx, the biggest opportunity for both materials is in printed and potentially printed electronics, where the value of these devices that partly incorporate these materials will reach over $44 billion in 2021.
