Crossover from diffusive to ballistic transport in semiconductor nanostructures
Dan Csontos, Sergio E. Ulloa
We present a detailed microscopic study of quasi-ballistic transport in deep submicron semiconductor channels. In particular, we study the crossover between the diffusive and balli…
Spin injection and accumulation in inhomogeneous semiconductors
Dan Csontos, Sergio E. Ulloa
We present a study of spin transport in charge and spin inhomogeneous semiconductor systems. In particular, we investigate the propagation of spin-polarized electrons through a bou…
Level structure and spin-orbit effects in semiconductor nanorod dots
C. L. Romano, S. E. Ulloa, P. I. Tamborenea
We investigate theoretically how the spin-orbit Dresselhaus and Rashba effects influence the electronic structure of quasi-one-dimensional semiconductor quantum dots, similar to th…
Multichannel field-effect spin barrier selector
G. E. Marques, A. C. R. Bittencourt, C. F. Destefani +1
We have studied spin carrier dynamics under full spin-orbit coupling. The anisotropy of dispersions for independent circular spinor polarizations is explored as a possible vertical…
Spin-orbit coupling and magnetic spin states in cylindrical quantum dots
C. F. Destefani, S. E. Ulloa, G. E. Marques
We make detailed analysis of each possible spin-orbit coupling of zincblende narrow-gap cylindrical quantum dots built in two-dimensional electron gas. These couplings are related…
