Abstract (English)

In our work we have employed a successful all electrical and all semiconductor spin injection scheme. Our samples base on a new class of so-called diluted magnetic semiconductors, namely its best known representative GaMnAs. In our experiments we were able to reliably achieve spin injection efficiencies of remarkably high 50% and slightly above. The results obtained from nonlocal in-plane ...

Translation of the abstract (German)

In dieser Arbeit wurde elektrische Spin-Injektion in einem komplett aus Halbleitern bestehendem Bauelement nachgewiesen. Unsere Proben basierten auf einer neuen Materialklasse von so genannten Verdünnten Magnetischen Halbleitern, insbesondere derem bekanntesten Vertreter GaMnAs. Wir konnten wiederholt bemerkenswert hohe Spin-Injektionseffizienzen von über 50% erzielen.Dabei waren die Ergebnisse ...
