Absorption of acoustic phonons in fluorinated carbon nanotubes with non-parabolic, double periodic band

Sekyi-Arthur, D.; Mensah, S. Y.; Mensah, N. G.; Dompreh, K. A.; Edziah, R. (University of Cape Coast, 2016)

We studied theoretically the absorption of acoustic phonons in the hypersound regime in Fluorine modified Carbon Nanotube (F-CNT) ΓF –CNT and compared it to that of undoped Single Walled Nanotube (SWNT) ΓSW NT .Per the ...
Acoustoelectric effect in degenerate carbon nanotube

Dompreh, K. A.; Mensah, N. G.; Mensah, S. Y.; Sam, F.; Twum, A.K. T (University of Cape Coast, 2015)

Acoustoelectric Effect AE in degenerate Carbon Nanotube (CNT) was theoretically studied for hypersound in the regime ql >> 1. The dependence of acoustoelectric current jac on the acoustic wave number ~ and frequency ωq at ...
Acoustoelectric effect in fluorinated carbon nanotube in the absence of external electric field

Sakyi-Arthur, D.; Mensah, S. Y.; Adu, K. W.; Dompreh, K. A.; Edziah, R.; Mensah, N. G (University of Cape Coast, 2020-01-23)

Acoustoelectric effect (AE) in a non-degenerate Fluorine modified single walled carbon nanotube (FSWCNT) semiconductor is studied theoretically using the Boltzmann’s transport equation. The study is done in the hyper sound ...
