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…

Point Contact Spin Spectroscopy of Ferromagnetic MnAs Epitaxial Films
R. Panguluri, G. Tsoi, B. Nadgorny +3
We use point contact Andreev reflection spin spectroscopy to measure the transport spin polarization of MnAs epitaxial films grown on (001) GaAs. By analyzing both the temperature…

Highly enhanced Curie temperatures in low temperature annealed (Ga,Mn)As epilayers
K. C. Ku, S. J. Potashnik, R. F. Wang +9
We report Curie temperatures up to 150 K in annealed Ga1-xMnxAs epilayers grown with a relatively low As:Ga beam equivalent pressure ratio. A variety of measurements (magnetization…
