Half-vortex sheets and domain-wall trains of rotating two-component Bose-Einstein condensates in spin-dependent optical lattices
Wei Han, Suying Zhang, Jingjing Jin +1
We investigate half-vortex sheets and domain-wall trains of rotating two-component Bose-Einstein condensates in spin-dependent optical lattices. The two-component condensates under…
Spin Transport and Relaxation in Graphene
Wei Han, K. M. McCreary, K. Pi +5
We review our recent work on spin injection, transport and relaxation in graphene. The spin injection and transport in single layer graphene (SLG) were investigated using nonlocal…
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…
Electrical spin injection and transport in Germanium
Yi Zhou, Wei Han, Li-Te Chang +7
We report the first experimental demonstration of electrical spin injection, transport and detection in bulk germanium (Ge). The non-local magnetoresistance in n-type Ge is observa…
