Fabrication and Characterization of Modulation-Doped ZnSe/(Zn,Cd)Se (110) Quantum Wells: A New System for Spin Coherence Studies
K. C. Ku, S. H. Chun. W. H. Wang, W. Fadgen +4
We describe the growth of modulation-doped ZnSe/(Zn,Cd)Se quantum wells on (110) GaAs substrates. Unlike the well-known protocol for the epitaxy of ZnSe-based quantum structures on…
Exchange Biasing of the Ferromagnetic Semiconductor (Ga,Mn)As by MnO
K. F. Eid, M. B. Stone, O. Maksimov +6
We provide an overview of progress on the exchange biasing of a ferromagnetic semiconductor (Ga1-xMnxAs) by proximity to an antiferromagnetic oxide layer (MnO). We present a detail…
Exchange Biasing of the Ferromagnetic Semiconductor Ga1-xMnxAs
K. F. Eid, M. B. Stone, K. C. Ku +4
We demonstrate the exchange coupling of a ferromagnetic semiconductor (Ga1-xMnxAs) with an overgrown antiferromagnet (MnO). Unlike most conventional exchange biased systems, the bl…
Spin-polarized Tunneling in Hybrid Metal-Semiconductor Magnetic Tunnel Junctions
S. H. Chun, S. J. Potashnik, K. C. Ku +2
We demonstrate efficient spin-polarized tunneling between a ferromagnetic metal and a ferromagnetic semiconductor with highly mismatched conductivities. This is indicated by a larg…
Effects of annealing time on defect-controlled ferromagnetism in Ga1-xMnxAs
S. J. Potashnik, K. C. Ku, S. H. Chun +3
We have studied the evolution of the magnetic, electronic, and structural properties of annealed epilayers of Ga1-xMnxAs grown by low temperature molecular beam epitaxy. Annealing…
Two-Carrier Transport in Epitaxially Grown MnAs
J. J. Berry, S. J. Potashnik, S. H. Chun +3
Magneto-transport measurements of ferromagnetic MnAs epilayers grown by molecular beam epitaxy reveal the presence of both positive and negative charge carriers. Electrical transpo…
