  • Direct current generation due to wave mixing in zigzag carbon nanotubes 
    Abukari, S. S.; Mensah, S.Y.; Mensah, N. G.; Dompreh, K. A.; Twum, A.; Allotey, F. K. A. (University of Cape Coast, 2000)
    Generation of direct current in zigzag carbon nanotubes due to harmonic mixing of two coherent electromagnetic waves is being considered. The electromagnetic waves have commensurate frequencies of Ω and Ω. The rectification ...
  • Generation and amplification of terahertz radiation in carbon nanotubes 
    Abukaria, S. S.; Mensah, S.Y.; Mensah, N. G.; Adud, K. W.; Rabiu, M.; Dompreh, K. A.; Twum, A. (University of Cape Coast, 2012)
    We investigate theoretically the feasibility of generation and amplification of terahertz radiation in aligned achiral carbon nanotubes (zigzag and armchair) in comparison with a super lattice in the presence of a constant ...
