Abstract

âº We compute the electron field emission current in nanostructures from first principles. âº Theoretical method applies time-dependent density functional theory. âº The method is applied to short carbon nanotubes and graphene sheets. âº Time propagation is obtained through the classical Crank-Nicholson method.
