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 ...
On the amplification of acoustic phonons in carbon nanotube

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

We present a theoretical study of acoustic phonons amplification in Carbon Nanotubes (CNT). The phenomenon is via Cerenkov emission (CE) of acoustic phonons using intraband transitions proposed by Mensah et. al., [1] in ...
Semiconductor fluorinated carbon nanotube as a low voltage current amplifier acoustic device

Sakyi-Arthur, D.; Mensah, S. Y.; Adu, K. W.; Dompreh, K. A.; Edziah, R.; Mensah, N.; Jebuni-Adanu, C. (University of Cape Coast, 2020-02-12)

Acoustoelectric effect (AE) in a non-degenerate fluorinated single walled carbon nanotube (FSWCNT) semiconductor was carried out using a tractable analytical approach in the hypersound regime q 1 , where q is the acoustic ...
