Acoustoelectric effect in degenerate carbon nanotube

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

Acoustoelectric Effect AE in degenerate Carbon Nanotube (CNT) was theoretically studied for hypersound in the regime ql >> 1. The dependence of acoustoelectric current jac on the acoustic wave number ~ and frequency ωq at ...
Amplification of acoustic waves in armchair graphene nanoribbon in the presence of external electric and magnetic field

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 field was studied using the Boltzmann’s kinetic equation. The general expression for the Amplification ...

Hypersound absorption of acoustic phonons in a degenerate carbon nanotube

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

Absorption of acoustic phonons was studied in degenerate Carbon Nanotube (i.e. where the electrons are found close to the Fermi level). The calculation of the hypersound absorption coefficient (Γ) was done in the regime ...
Spatial distribution of electric field strength at a teaching hospital premises due to transmissions between 87.5 mhz and 2.6 ghz

Azah, C. K.; Amoako, J. K.; Sam, F. (University of Cape Coast, 2018)

A radiofrequency (RF) electromagnetic radiation safety assessment had been carried out at public access points within the compound of a teaching hospital. The frequency band investigated ranged from 87.5 MHz to 2.6 GHz. ...
