Abstract
One and two dimensional nanocarbon (NC) materials, including carbon nanotubes (CNTs), graphene and graphene nanoribbons (GNRs) have excellent properties and can therefore be building blocks of future electronic devices. It has been predicted and demonstrated that transistor channels and interconnects (More Moore devices) made of NC materials have excellent properties [1-6]. NC-based Beyond CMOS and More than Moore (MtM) devices have also been proposed and demonstrated [6-10]. In this paper, we briefly review some of MtM or functional devices using NC materials, which include terahertz (THz) wave detectors, strain sensors, and gas sensors. A novel gas sensor based on a graphene-gate transistor we have recently developed [11] is also described.
