Resonance Transmission

In this paper, we investigate effects of the Dresselhaus spin-orbit coupling, inter-well coupling, and external bias on the dynamics of resonance tunneling through a semiconductor double-well structure. Based on the transfer matrix technique and the single band effective-mass approximation method, the numerical results demonstrate that the transmission peaks of the spin-up and spin-down electrons split due to the Dresselhaus spin-orbit coupling in the double-well structure. As the in-plane wave vector and external electric field increase, the split becomes farther apart. There is a prominent difference between the lifetime of the quasibound energy level for different spin-polarized electrons. The spin-dependent tunneling time is obtained using the time-dependent Schrödinger equation.

The Continuum

Recent experimental work on (e,2e) coincidences involving polarized electrons is reviewed. The origin of the observed spin asymmetries are exchange effects, spin-orbit interaction of the continuum electrons, and spin-orbit coupling within the target in conjunction with orbital orientation and exchange. These mechanisms are explained in some detail. Experimental and theoretical investigations of spin effects have been performed for ionization of outer shell electrons as well as for ionization of inner shell electrons.
