Acoustoelectric Effect in Graphene with degenerate Energy dispersion

Abstract

The acoustoelectric effect $AE$ in Graphene with degenerate energy dispersion is theoretically studied for hypersound in the regime $ql>>1$. At low temperatures ($k_{\beta }T<<1$), the non-linear dependence of Acoustoelectric current $j/j_0$ on the frequency ${\omega }_q$ and temperature $T$ are numerically analysed. The obtained graph for $j/j_0$ against ${\omega }_q$ qualitatively agreed with an experimentally obtained results. For $j/j_0$ versus $T$, the dependence of Acoustoelectric current in Graphene was found to manifest at low temperatures.
