Flexible Logic Circuits by using Van Der Waals Contacted Graphene Field-Effect Transistors

摘要

This paper presents van der Waals (vdW) contacted graphene field-effect transistors (GFETs) and logic circuits, both on rigid and flexible substrates. These logic gates exhibit stable performances after 100 cycles of bending. Realized with complementary metal oxide semiconductor (CMOS) compatible technology, the vdW contacted GFETs show performance comparable to the top-contacted GFETs and thus present excellent cost-effective alternatives to top- and edge-contacted GFETs for large-area electronic applications.
