This paper considers dimensionally-confined graphene quantum dots, provides formulations for the electronic states and the optical phonons in these quantum dots. These results are used to calculate scattering rates for the optical deformation potential and phonon bottleneck effects are identified.

Recently graphene has been studied in view of its promise as a material for high-performance electronics. In order to advance the basic understanding of graphene and graphite for graphene-based devices it is necessary to study the phonon modes in these materials as well as their interactions with charge carriers. Moreover, it is necessary to understand the phonon-based thermal properties of these...
