Electron g-factor anisotropy in asymmetric GaAs/AlGaAs quantum well
Kalevich V. K. , Korenev V. L.
It is shown that in an asymmetric quantum well, grown in the direction ζ 11 [001] from semiconductors with a zinc blende structure, the conduction-band spin splitting attributable to the absence of an inversion center results in conduction-electron g-factor anisotropy in the plane of the well. It is demonstrated for the example of a GaAs/AlGaAs quantum well that the off-diagonal components gxy=gyx (x||[100]); which characterize the electron g-factor anisotropy in the plane of the well, can be comparable in magnitude to the diagonal components gxx=gyy-
