ABSTRACT
In this chapter, we present the overview of our recent studies on the electron spectrum and the density of states of longwave electrons in curved graphene nanoribbons, based on the Dirac equation in a curved space-time. The current-voltage characteristics for the contact of nanoribbon-quantum dots and nanoribbon-metal have been revealed. The dependence of the specimen properties on its geometry was analyzed. Also the regions with negative differential conductivity were found.
