Talk at 217th ECS Meeting - Vancouver - 27 april 2010
The perspective of graphene-based electronics ranks high among the many reasons for the explosive growth of interest in graphene in recent years. Graphene has very promising and intriguing transport properties, but also a serious drawback for electronics: it has no native energy gap, precluding the possibility of shutting off device current.
In the talk we shall discuss the relative advantages and disadvantages of the different technology options for inducing a bandgap in graphene. The small attainable energy gap and mobility degradation still remain the main challenges towards large-scale integration of graphene-based nanoelectronics.
