Paper Abstract

In this paper, the valence band spin-splitting for the strained superlattices composed of AlyGa1-yAs, AlxGa1-xAs and GaAs was studied. By varying the material compositions or the layer thickness, we observed that the subbands corresponding to the spin-up and spin-down split when the superlattices unit-cell is asymmetrical about the cell center. The spin-splitting is defined as the splitting for both spin-up and spin-down in a spin degenerate subband. Moreover, the splitting mainly occurs at the region where the heavy hole and light hole interact on each other strongly.
