Generation and amplification of terahertz radiation in carbon nanotubes

Abukaria, S. S.; Mensah, S.Y.; Mensah, N. G.; Adud, K. W.; Rabiu, M.; Dompreh, K. A.; Twum, A. (University of Cape Coast, 2012)

We investigate theoretically the feasibility of generation and amplification of terahertz radiation in aligned achiral carbon nanotubes (zigzag and armchair) in comparison with a super lattice in the presence of a constant ...
Nonlinear conductivity in graphene

Abukaria, S. S.; Mensah, S. Y.; Musah, R.; Mensah, N. G.; Dompreh, K. A. (University of Cape Coast, 2015)

We consider the tight-binding approximation for the description of energy bands of graphene, together with the standard Boltzmanns transport equation and constant relaxation time, an expression for the conductivity was ...
Stark-cyclotron resonance in an array of carbon nanotubes

Abukaria, S. S.; Mensah, S. Y.; Musah, R.; Mensah, N. G.; Dompreh, K. A. (University of Cape Coast, 2015)

Using the kinetic approach based on the semiclassical Boltzmanns transport equation with constant relaxation time, we theoretically studied the Stark cyclotron resonance in an array of carbon nanotubes. Exact expression ...
