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…
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…
Tunneling Spin Injection into Single Layer Graphene (Supplementary Information)
Wei Han, K. Pi, K. M. McCreary +4
We achieve tunneling spin injection from Co into single layer graphene (SLG) using TiO2 seeded MgO barriers. A non-local magnetoresistance (ΔRNL) of 130 Ω is observed at room tempe…
Manipulation of Spin Transport in Graphene by Surface Chemical Doping
K. Pi, Wei Han, K. M. McCreary +3
The effects of surface chemical doping on spin transport in graphene are investigated by performing non-local measurements in ultrahigh vacuum while depositing gold adsorbates. We…
The Effect of Cluster Formation on Graphene Mobility
K. M. McCreary, K. Pi, Adrian Swartz +6
We investigate the effect of gold (Au) atoms in the form of both point-like charged impurities and clusters on the transport properties of graphene. Cryogenic deposition (18 K) of…
Tunneling Spin Injection into Single Layer Graphene

We achieve tunneling spin injection from Co into single layer graphene (SLG) using TiO2 seeded MgO barriers. A non-local magnetoresistance (ΔRNL) of 130 Ω is observed at room tempe…
Electrical Detection of Spin Precession in Single Layer Graphene Spin Valves with Transparent Contacts
Wei Han, K. Pi, W. Bao +5
Spin accumulation and spin precession in single-layer graphene are studied by non-local spin valve measurements at room temperature. The dependence of the non-local magnetoresistan…
Electron-Hole Asymmetry of Spin Injection and Transport in Single-Layer Graphene
Wei Han, W. H. Wang, K. Pi +6
Spin-dependent properties of single-layer graphene (SLG) have been studied by non-local spin valve measurements at room temperature. Gate voltage dependence shows that the non-loca…
Electronic Doping and Scattering by Transition Metals on Graphene
K. Pi, K. M. McCreary, W. Bao +6
We investigate the effects of transition metals (TM) on the electronic doping and scattering in graphene using molecular beam epitaxy combined with in situ transport measurements.…
