Integrating graphene into electrical devices using a boron nitride gate

Summary

Metal oxide semiconductor (MOS) field-effect transistors (FETs) are elementary components in digital integrated circuits. With the expanding need for greater computational power driving development of modern microelectronics, FETs must be smaller, faster, and more efficient. New technologies employing a wider range of materials with unique properties are necessary since the scaling-down of silicon-based technology will encounter the limits of the atomic level. Graphene (a single layer of graphite) has been heavily investigated for over a decade as a new material for next generation FETs. This technology describes an improvement in graphene performance by introducing a boron nitride film to incorporate graphene into integrated circuits. The technology’s method of incorporating graphene into FETs can be adopted commercially and provides superior FETs compared to current silicon-dioxide supported devices.
