Abstract

Formerly, we proposed an approach to construct new graphene-based elements for nanoelectronics with different properties using "lines" of chemisorbed H atom pairs on a graphene surface. According to band structure calculations these H-C "lines" change the electronic spectrum of pure graphene, forming quasi-one-dimensional electronic waveguides. The periodic "line" superlattices have semiconductor or metallic electronic structures according to their geometry, similar to the case of carbon nanotubes. We calculated the propagation of electronic wave packets parallel to the H-C line. The results make it possible to gain insight into the details of electron transport in nanoelectronic devices made of line superlattices.
