Laser Stimulated Thermal Conductivity in chiral carbon nanotube
A. Twum, S. Y. Mensah, N. G. Mensah +3
An investigation of laser stimulated thermal conductivity in chiral CNT is presented. The thermal conductivity of a chiral CNT is calculated using a tractable analytical approach.…
External electric field effect on electron transport in carbon nanotubes
S. S. Abukari, S. Y. Mensah, N. G. Mensah +3
Electronic transport properties of carbon nanotubes are studied theoretically in the presence of external electric field E(t) by using the Boltzmann's transport with constant relax…
Appearance of Large Amplitude Current Dynamics as a Result of Bragg Reflection in Carbon Nanotubes
S. S. Abukari, S. Y. Mensah, N. G. Mensah +4
We report on theoretical analysis of large amplitude current dynamics due to Bragg reflections in carbon nanotubes exposed to an external electric field. Using the kinetic equation…
Appearance of Negative Differential Conductivity in Graphene Nanoribbons at High-Harmonics
M. Rabiu, S. Y. Mensah, S. S. Abukari
We theoretically study current dynamics of graphene nanoribbons subject to bias dc and ac driven fields. We showed that graphene nanoribbons exhibit negative high-harmonic differen…
Generation and Amplification of Terahertz Radiation in Carbon Nanotubes
S. S. Abukari, S. Y. Mensah, N. G. Mensah +4
We investigate theoretically the feasibility of generation and amplification of terahertz radiation in aligned achiral carbon nanotubes (zigzag and armchair) in comparison with a s…
Photon-Assisted Process and High-Harmonic Dynamic Localization in Graphene Nanoribbons
M. Rabiu, S. Y. Mensah, S. S. Abukari
We used a complete tight-binding band structure of graphene nanoribbon to obtain, for the first time, analytical techniques for observing photon assisted transport, and dynamic loc…
