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 ...
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 ...
Thermoelectric amplification of phonons in graphene

Dompreh, K. A.; Mensah, N. G.; Mensah, S. Y.; Fosuhene, S. K. (University of Cape Coast, 2016-07-07)

Amplification of acoustic in-plane phonons due to an external temperature gradient (rT) in single-layer graphene (SLG) was studied theoretically. The threshold temperature gradient ðrTÞ g 0 and the threshold voltage ðVTÞ ...
