Title
Theory of electron energy spectrum and Aharonov-Bohm effect in self-assembled $In_{x}Ga_{1-x}As$ quantum rings in GaAs
Author
Abstract
 We analyze theoretically the electron energy spectrum and the magnetization of an electron in a strained In(x)Ga(1-x)As/GaAs self-assembled quantum ring (SAQR) with realistic parameters, determined from the cross-sectional scanning-tunneling microscopy characterization of that nanostructure. The SAQRs have an asymmetric indium-rich craterlike shape with a depression rather than an opening at the center. Although the real SAQR shape differs strongly from an idealized circular-symmetric open ring structure, the Aharonov-Bohm oscillations of the magnetization survive.
