Spin-dependent transport in the p-type ultra-narrow silicon quantum well

Authors

Description

We present the findings of the spin-dependent transport of the 2D holes in the p-type ultra-narrow self-assembled silicon quantum well (Si-QW) confined by the superconductor barriers on the n-type Si (100) surface. The Aharonov-Casher conductance oscillations caused by the Rashba spin-orbit interaction are found to interplay with the quantization phenomena induced by the creation of the two-dimensional subbands in Si-QW and the quantum subbands due to the Andreev reflection from the superconductor barriers.
