Electron-electron interaction correction and magnetoresistance in tilted fields in Si-based two-dimensional systems
We study the diffusive electron-electron interaction correction to conductivity by analyzing simultaneously ${\ensuremath{\rho}}_{xx}$ and ${\ensuremath{\rho}}_{xy}$ for disordered 2D electron systems in Si in a tilted magnetic field. Tilting the field is shown to be a straightforward tool to disentangle spin and orbital effects. In particular, by changing the tilt angle …
