Disorder enhances thermoelectric figure of merit in armchair graphane nanoribbons

We study the thermoelectric property of graphane strips by using density functional theory calculations combined with the nonequilibrium Green's function method. It is found that figure of merit ( Z T ) can be remarkably enhanced five times by randomly introducing hydrogen vacancies to the grap...
