Formula for the Absorption Coefficient for Multi-Wall Nanotubes
Godfrey Gumbs, Antonios Balassis
We present a formalism for calculating the absorption coefficient of a pair of coaxial tubules. A spatially nonlocal, dynamical self-consistent field theory is obtained by calculat…
Model of plasmon excitations in a bundle and two-dimensional array of nanotubes
Tibab McNeish, Godfrey Gumbs, Antonios Balassis
We calculate the plasma excitations in a bundle as well as a two-dimensional (2D) periodic array of aligned parallel multishell nanotubes on a substrate. The carbon nanotubes are o…
Enhanced response of current-driven coupled quantum wells
Antonios Balassis, Godfrey Gumbs
We have investigated the conditions necessary to achieve stronger Cherenkov-like instability of plasma waves leading to emission in the terahertz (THz) regime for semiconductor qua…
Energy bands, conductance and thermoelectric power for ballistic electrons in a nanowire with spin-orbit interaction
Godfrey Gumbs, Antonios Balassis, Danhong Huang
We calculated the effects of spin-orbit interaction (SOI) on the energy bands, ballistic conductance and the electron-diffusion thermoelectric power of a nanowire by varying the te…
