The Difference

Spin diffusion in the finite magnetic heterojunction was explored considering the spin dependent conductivity. In organic semiconductor spintronic devices, the up-spin and down-spin polarons have different density once spin injection happens from ferromagnetic electrodes into organic semiconductors. The difference results in the spin dependent conductivity. The calculations show that the spin injection efficiency is dependent on the spin dependent conductivity and the size of the layers. The spin dependent conductivity has great influence on the spin injection efficiency in the finite magnetic heterojunction, when the spin polarization of the organic semiconductors is moderate.

High Potential Barrier

The electroluminescence properties of ferromagnetic GaMnSb/GaAs diodes have been investigated. It has been found that diodes properties are significantly dependent on GaMnSb layer electrical properties. The intensity of electroluminescence of the diode with semiconductor GaMnSb contact is relatively low, that is due to a high potential barrier at the interface. In case of metallic GaMnSb/GaAs contact high hole injection efficiency provides relatively high electroluminescence intensity. Investigated light-emitting diodes can be prospective for investigation of spin injection effects.
