Surface Vibrational Modes in Multilayer Graphene
POSTER
Abstract
The surface vibrational modes in multilayer graphene are studied based on both density-functional theory and the force constant model. It is found that these modes are mainly localized on the surface layers. The relationship between these modes and the stacking order as well as the layer number will be discussed.
