Abstract
The pulsation measurement of electron spin quantum beats by time resolved photoluminescence in a magnetic field perpendicular or at to the growth axis yields the transverse and longitudinal components of the electron Landé g factor in GaAs quantum wells (QW). The anisotropy of the g factor is thus determined as a function of the well width. No difference is found between the components of the g factor parallel and perpendicular to the growth axis for a 12 nm wide QW, whereas a clear anisotropy is measured for narrower QW.Keywords
