摘要：

This paper presents an analytical displacements and dispersion relations for optical phonons of a graphene sheet. These results are used to derive the optical deformation potential interactions for graphene as well as to obtain descriptions of the confined optical phonons for graphene. (C) 2009 Elsevier Ltd.
