Spin Susceptibility of Two-Dimensional Electrons in Narrow AlAs Quantum Wells
Spin Susceptibility of Two-Dimensional Electrons in Narrow AlAs Quantum Wells
We report measurements of the spin susceptibility in dilute two-dimensional electrons confined to a 45 A wide AlAs quantum well. The electrons in this well occupy an out-of-plane conduction-band valley, rendering a system similar to two-dimensional electrons in Si-MOSFETs but with only one valley occupied. We observe an enhancement of …
