摘要
We present spin-unpolarized DFT study for band structures, density of states and transmission of armchair graphene nanoribbons (AGNRs) using local density approximations (LDA). The band gaps of AGNRs were found to vary randomly with the width of ribbon and they show semiconducting behavior. We have used oxygen as a dopant in AGNRs and observed the metallicity and half-metallicity in AGNRs. The transports are highly influenced by edge doping of oxygen in AGNRs. Since transmissions in AGNRs are oxygen sensitive, so they can be used for sensor applications.
