Enhancement of Spin Injection into Graphene by Water Dipping
K. M. McCreary, Hua Wen, H. Yu +3
We immerse single layer graphene spin valves into purified water for a short duration (<1 min) and investigate the effect on spin transport. Following water immersion, we observe a…
Metallic and Insulating Adsorbates on Graphene
K. M. McCreary, K. Pi, R. K. Kawakami
We directly compare the effect of metallic titanium (Ti) and insulating titanium dioxide (TiO2) on the transport properties of single layer graphene. The deposition of Ti results i…
Optically-patterned nuclear doughnuts in GaAs/MnAs heterostructures
J. Stephens, J. Berezovsky, R. K. Kawakami +2
We demonstrate a scheme for optically patterning nuclear spin polarization in semiconductor/ferromagnet heterostructures. A scanning time-resolved Kerr rotation microscope is used…
Independent Electronic and Magnetic Doping in (Ga,Mn)As Based Digital Ferromagnetic Heterostructures
E. Johnston-Halperin, J. A. Schuller, C. S. Gallinat +6
Ferromagnetic semiconductors promise the extension of metal-based spintronics into a material system that combines widely tunable electronic, optical, and magnetic properties. Here…
