Behaviour of hot electrons under the dc field in chiral carbon nanotubes
M. Amekpewu, K. A. Dompreh, S. Y. Mensah +5
Behaviour of hot electrons under the influence of dc field in carbon nanotubes is theoretically considered. The study was done semi-classically by solving Boltzmann transport equat…
On the amplification of acoustic phonons in carbon nanotube
K. A. Dompreh, N. G. Mensah, D. Sakyi-Arthur +1
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 transit…
Influence of external temperature gradient on acoustoelectric current in graphene
K. A. Dompreh, N. G. Mensah, S. Y. Mensah +1
Recent analyses of thermoelectric amplification of acoustic phonons in Free-Standing Graphene (FSG) have prompted the theoretical study of the influence of external te…
Absorption of acoustic phonons in Fluorinated Carbon Nanotubes with non-parabolic, double periodic band
D. Sekyi-Arthur, S. Y. Mensah, N. G. Mensah +2
We studied theoretically the absorption of acoustic phonons in the hypersound regime in Fluorine modified Carbon Nanotube (F-CNT) and compared it to that of undoped S…
