Tuning Spin Dynamics and Localization Near the Metal-Insulator Transition in Fe/GaAs heterostructures
Yu-Sheng Ou, N. J. Harmon, Patrick Odenthal +3
We present a simultaneous investigation of coherent spin dynamics in both localized and itinerant carriers in Fe/GaAs heterostructures using ultrafast and spin-resolved pump-probe…
Exchange-driven spin relaxation in ferromagnet/oxide/semiconductor heterostructures
Yu-Sheng Ou, Yi-Hsin Chiu, N. J. Harmon +6
We investigate electron spin relaxation in GaAs in the proximity of a Fe/MgO layer using spin-resolved optical pump-probe spectroscopy, revealing a strong dependence of the spin re…
Direct comparison of graphene devices before and after transfer to different substrates
Raymond Sachs, Zhisheng Lin, Patrick Odenthal +2
The entire graphene field-effect-transistor (FET) devices first fabricated on SiO2/Si are peeled from the surface and placed on a different wafer. Both longitudinal and transverse…
Integrating MBE materials with graphene to induce novel spin-based phenomena
Adrian G. Swartz, Kathleen M. McCreary, Wei Han +8
Magnetism in graphene is an emerging field that has received much theoretical attention. In particular, there have been exciting predictions for induced magnetism through proximity…
Effect of in-situ deposition of Mg adatoms on spin relaxation in graphene
Adrian G. Swartz, Jen-Ru Chen, Kathleen M. McCreary +3
We have systematically introduced charged impurity scatterers in the form of Mg adsorbates to exfoliated single layer graphene and observe little variation of the spin relaxation t…
