Abstract
A different approach to calculate the I−V characteristics of p+(Ga,Mn)As/n+GaAs spin injectors is presented. The vanishing of the spin-extraction transmission coefficients at the spin-split valence-band edges leads us to predict a dip or plateau in the I−V characteristics of this kind of diodes. We show that this minimum, or the inflection point, shifts with the exchange energy. Within this ...
