Abstract
Acoustoelectric current (jac) in Free-Standing Graphene (FSG) having degenerate energy dispersion at low temperatures T⪡TBG (TBG is the Block-Gruneisen temperature) was studied theoretically. We considered electron interaction with in-plain acoustic phonons in the hypersound regime (sound vibration in the range 109â1012Hz). The obtained expression for jac was numerically analyzed for various temperatures (T) and frequencies (Ïq) and graphically presented. The non-linear dependence of jac on Ïq varied with temperature. This qualitatively agreed with an experimentally obtained result which deals with temperature dependent acoustoelectric current in graphene [21].
