Phonon modulation of the spin-orbit interaction as a spin relaxation mechanism in InSb quantum dots
A. M. Alcalde, C. L. Romano, L. Sanz +1
We calculate the spin relaxation rates in a parabolic InSb quantum dots due to the spin interaction with acoustical phonons. We considered the deformation potential mechanism as th…

Electric field inversion asymmetry: Rashba and Stark effects for holes in resonant tunneling devices
H. B. de Carvalho, M. J. S. P. Brasil, V. Lopez-Richard +7
We report experimental evidence of excitonic spin-splitting, in addition to the conventional Zeeman effect, produced by a combination of the Rashba spin-orbit interaction, Stark sh…
Confined polar optical phonons in semiconductor double heterostructures: an improved continuum approach
F. Comas, I. Camps, N. Studart +1
Confined polar optical phonons are studied in a semiconductor double heterostructure (SDH) by means of a generalization of a theory developed some years ago and based on a continuo…
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…
The violation of the Hund's rule in semiconductor artificial atoms
C. F. Destefani, J. D. M. Vianna, G. E. Marques
The unrestricted Pople-Nesbet approach for real atoms is adapted to quantum dots, the man-made artificial atoms, under applied magnetic field. Gaussian basis sets are used instead…
