| Abstract: | The acoustoelectric effect AE in Graphene with degenerate energy dispersion is theoretically studied for hypersound in the regime ql >> 1. At low temperatures (kβT << 1), the non-linear dependence of Acoustoelectric current j/j0 on the frequency ωq and temperature T are numerically analysed. The obtained graph for j/j0 against ωq qualitatively agreed with an experimentally obtained results. For j/j0 versus T, the dependence of Acoustoelectric current in Graphene was found to manifest at low temperatures |
