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…
Nonlinear Conductivity in Graphene
S. S. Abukari, S. Y. Mensah, R. Musah +2
We consider the tight-binding approximation for the description of energy bands of graphene, together with the standard Boltzmann's transport equation and constant relaxation time,…
Hot electrons injection in carbon nanotubes under the influence of quasi-static ac-field
M. Amekpewu, S. Y. Mensah, R. Musah +3
Hot electrons injection in carbon nanotubes (CNTs ) where in addition to applied dc field (), there exist simultaneously a quasi-static ac electric field (i.e. when the…
High Frequency Conductivity of Hot Electrons in Carbon Nanotubes
M. Amekpewu, S. Y. Mensah, R. Musah +3
High frequency conductivity of hot electrons in an undoped single walled achiral carbon nanotubes (CNTs) under the influence of ac-dc driven fields is considered. We investigated s…
