Abstract :
In this contribution we report and discuss that a different combination of Schottky barrier materials leads to a large increase of the transfer ratio between emitter and collector current, without increasing the input (emitter) current in a spin valve transistor structure. It will be shown that a different combination of Schottky barrier materials (for example replacing Si/metal ferromagnetic by porous silicon/metal ferromagnetic) leads to a large increase of the transfer ratio
