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…
Amplification of Hypersound in Graphene with degenerate energy dispersion
Kwadwo A. Dompreh, Natalia G. Mensah, Samuel Y. Mensah
Hypersound amplification/absorption of acoustic phonons in Graphene with degenerate energy dispersion near the Fermi level was theoretically studied. For $k_βT <<…
Amplification of acoustic phonons in superlattice
Kwadwo A. Dompreh, Samuel Y. Mensah, Natalia G. Mensah +3
The amplification of acoustic phonons in a superlattice in the presence of an electric field has been investigated theoretically and numerically by computati…
