Novel functional devices by using nanocarbon materials

Abstract

Nanocarbon materials, including graphene and carbon nanotubes (CNTs) have excellent electrical, thermal, and mechanical properties, and are expected to be used for various applications. Some of applications, such as the use of CNTs as conductive additives for lithium ion batteries, have already been realized. The application of nanocarbon materials to electronic devices, however, has not had great success as of yet. We have actually been working on such applications. Our targets include More Moore applications, such as a transistor and interconnect for large scale integrated circuits (LSIs), and More-than-Moore ones, such as a gas sensor and a detector diode for high-frequency waves. In this article, we briefly review More Moore and More-than-Moore applications of nanocarbon materials. Furthermore, we describe our recent efforts to develop novel functional devices.
