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.
