Anisotropy of electron Lande g-factor in (110) GaAs quantum wells — •Sergej Kunz¹, Stefan Oertel¹, Jens Hübner¹, Dieter Schuh², Werner Wegscheider², and Michael Oestreich¹ — ¹Universität Hannover, Institut für Festkörperphysik, Abteilung Nanostrukturen, Appelstr. 2, D-30167 Hannover — ²Universität Regensburg, Institut für Experimentelle und Angewandte Physik, D-93040 Regensburg

We measure the electron Lande g-factor and electron spin lifetime in (110)-oriented GaAs quantum wells by time- and polarization resolved photoluminescence spectroscopy. The electron Lande g-factor shows an anisotropy on the in plane magnetic field direction and this anisotropy is investigated in detail for different quantum well widths. Furthermore, the electron spin dynamics is determined in dependence on quantum well widths and spin orientation.
