Amplification of acoustic waves in armchair graphene nanoribbon in the presence of external electric and magnetic fields

Dompreh, K.A.; Mensah, S.Y.; Abukari, S.S.; Sam, F.; Mensah, N.G. (University of Cape Coast, 2015)

Amplification of acoustic waves in Armchair Graphene Nanoribbon (AGNR) in the presence of an external electric and magnetic fields was studied using the Boltzmann's kinetic equation. The general expression for the amplification ...
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 ...
