Effect of current hysteresis on the spin polarization of current in a paramagnetic resonant tunneling diode

P. Wojcik, B. J. Spisak, M. Woloszyn +1

A spin-dependent quantum transport is investigated in a paramagnetic resonant tunneling diode (RTD) based on a Zn${}_{1-x}$Mn${}_x$Se/ZnBeSe heterostructure. Using the Wigner-Poisson m…
