摘要：
Light absorption in graphene nanoribbons is studied analytically and numerically. Due to size quantization, the electronic states in the nanoribbon form a set of one-dimensional subbands modifying remarkably the absorption coefficient. The electronic subbands are calculated using the Berry-Mondragon boundary conditions at the nanoribbon edges, which are applicable for nanoribbons of the armchair type. Numerical results on pseudospin (sublattice) density generation by light absorption are presented and discussed.
