Abstract
The field of semiconductor spintronics has pursued the development of novel device architectures exploiting the spin degree of freedom in addition to, or in place of, traditional charge based functionality. In particular, theoretical modeling has predicted that the addition of a magnetic base layer to a bipolar junction transistor has the potential to serve as an exceptionally efficient spin filter, add intrinsically non-volatile functionality and exhibit extremely fast switching. Here, we present the experimental implementation of this scheme via the inclusion of a digitally-doped (Ga, Mn) As layer into the p region of an n-p-n III-As heterojunction bipolar transistor. These proof of principle devices exhibit gain greater than one, concurrent with robust ferromagnetism, which demonstrates a critical step in the development of an active spin functional device architecture.
