Anisotropic spin splitting of the electron ground state in InAs quantum dots

Abstract

Photoinduced circular dichroism experiments in an oblique magnetic field allow measurements of Larmor precession frequencies, and so give a precise determination of the electron Lande g factor and its anisotropy in self-assembled InAs/GaAs quantum dots emitting at 1.32 eV. In good agreement with recent theoretical results, we measure g perp= 0.397 +_ 0.003 and g par = 0.18 +- 0.02.
