Anisotropic electron g-factor in quantum dots with spin-orbit interaction | | C. F. Destefani

3 Nov 2004 | | Subject: | Mesoscopic Systems and Quantum Hall Effect; Materials Science | cond-mat.mes-hall cond-mat.mtrl-sci | | Abstract: | g-factor tuning of electrons in quantum dots is studied as function of in-plane and perpendicular magnetic fields for different confinements. Rashba and Dresselhaus effects are considered, and comparison is made between wide- and narrow-gap materials. The interplay between magnetic fields and intrinsic spin-orbit coupling is analyzed, with two distinct phases found in the spectrum for GaAs in perpendicular field. The anisotropy of the g-factor is reported, and good agreement with available experimental findings is obtained. | | Source: | arXiv, cond-mat/0411071 | | Services: | Forum | Review | PDF | Favorites | |
