Abstract

Flexible organic electronic holds today promise of a new class of devices which offer possibility of large scale manufacturing, low cost, lightweight and mechanical flexibility. But combining high speed, high functionality and compatibility with plastic substrates is particularly challenging. Today, one estimates that carbon allotropes such as carbon nanotube and graphene combine all the necessary properties to meet this challenging goal. In particular, graphene material exhibits the very high carrier mobility allows targeting high frequency circuits on flexible substrate. Our graphene transistors fabricated using solution-based graphene show extrinsic current gain cutoff frequencies of 2.2 GHz and power gain cutoff frequencies of 550 MHz.
