Abstract:

Since it was first demonstrated that graphene could be successfully exfoliated from a graphite flake in 2004, two-dimensional materials have emerged as one of the most promising candidate materials for future electronic and optoelectronic applications due to their unique electrical and optical properties. However, graphene has been shown to possess almost no electronic band gap, which makes it unsuitable as a channel material in transistors because it cannot be used to switch off the trans...
