Abstract

Acoustoelectric Effect AE in degenerate Carbon Nanotube (CNT) was theoretically studied for hypersound in the regime ql >> 1. The dependence of acoustoelectric current j^ac on the acoustic wave number q and frequency ω_q at T = 10K and scattering angle (θ> 0) was evaluated at various harmonics n =± 1, 2, ... (where n is an integer). In the first harmonics (n = ± 1), the non-linear dependence of j^ac on ω_q and q were obtained. For n = ± 2, the numerically evaluated j^ac qualitatively agreed with an experimentally obtained result.
