Crystallographic anisotropy of the Zeeman splitting in 1D hole quantum wires

In this work we study the Zeeman splitting in induced ballistic 1D wires fabricated along two orthogonal crystallographic directions [2¯33] and [011¯]. Our data shows that the g  -factor anisotropy for the high symmetry [011¯] direction can be explained by the 1D confinement only, whereas in the case of [2¯33] direction, the interaction between the 1D confinement and crystal anisotropy effects is evident.
