Vacuum Annealed Cu contacts for graphene electronics
C. E. Malec, B. Elkus, D. Davidovic
We present transfer-length-method measurements of the contact resistance between Cu and graphene, and a method to significantly reduce the contact resistance by vacuum annealing. E…
Evidence for incompressible states in a metal graphene tunnel junction in high magnetic field
C. E. Malec, D. Davidović
We present transport measurements of tunnel junctions made between Cu and graphene in a magnetic field. We observe a transition to a Landau level like structure at high fields, as…
Electronic Properties of Clean Au-Graphene Contacts
C. E. Malec, D. Davidović
The effects of Au grains on graphene conduction and doping are investigated in this report. To obtain a clean Au-graphene contact, Au grains are deposited over graphene at elevated…
Transport in Graphene Tunnel Junctions
C. E. Malec, D. Davidovic
We present a technique to fabricate tunnel junctions between graphene and Al and Cu, with a Si back gate, as well as a simple theory of tunneling between a metal and graphene. We m…
Tunable Spin Filtering through an Aluminum Nanoparticle
F. T. Birk, C. E. Malec, D. Davidovic
Spin-polarized current through an Al nanoparticle in tunnel contact with two ferromagnets is measured as a function of the direction of the applied magnetic field. The nanoparticle…
Modelling Electron Spin Accumulation in a Metallic Nanoparticle
Y. G. Wei, C. E. Malec, D. Davidović
A model describing spin-polarized current via discrete energy levels of a metallic nanoparticle, which has strongly asymmetric tunnel contacts to two ferromagnetic leads, is presen…
