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 ...
Comparison of phonon-plasmon interaction in selected nanoparticle doped bulk and monolayer piezoelectric semiconductors in the presence of combined dc-ac fields

Otwey, Richard (UCC, 2020-10)

As semiconductor plasma medium experiences the spread of an acoustic wave, the wave reacts with several basic excitations. An example of such excitations is plasmon. In such a reaction in the presence of certain physical ...
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 ...
Optimizing the Thermo-physical Properties of Fluorinated Carbon Nanotube for Thermoelectric Applications

Sekyi-arthur, Daniel (Universtity of Cape Coast, 2020-07)

ABSTRACT In a nondegenerate fluorinated single-walled carbon nanotube (FSWCNT) in the hypersound domain, q` 1, where q is the acoustic wavenumber and ` is the carrier mean free path, a theoretical study of semiclassical ...
Variation in the susceptibility of tomato (Lycopersicon solanum L.) genotypes to tomato yellow leaf curl virus (TYLCVD) infections at coastal savannah and forest zones of Ghana

X Asare-Bediako, Doris Mensah; Wonkyi, Doris Mensah; Puije, Grace Van der; Amenorpe, Godwin; . Osei, Michael K (University of Cape Coast, 2017)

Little information is available on the resistance level of tomato genotypes to tomato yellow leaf curl virus disease (TYLCVD) and vector. Thirty-six genotypes representing the current available and accessible tomato germplasm ...
