Thermoelectric spin voltage in graphene
Juan F. Sierra, Ingmar Neumann, Jo Cuppens +3
In recent years, new spin-dependent thermal effects have been discovered in ferromagnets, stimulating a growing interest in spin caloritronics, a field that exploits the interactio…
Enhanced spin accumulation at room temperature in graphene spin valves with amorphous carbon interfacial layers
I. Neumann, M. V. Costache, G. Bridoux +2
We demonstrate a large enhancement of the spin accumulation in monolayer graphene following electron-beam induced deposition of an amorphous carbon layer at the ferromagnet-graphen…
Hot-Carrier Seebeck Effect: Diffusion and Remote Detection of Hot Carriers in Graphene
J. F. Sierra, I. Neumann, M. V. Costache +1
We investigate hot carrier propagation across graphene using an electrical nonlocal injection/detection method. The device consists of a monolayer graphene flake contacted by multi…
Fingerprints of Inelastic Transport at the Surface of the Topological Insulator Bi2Se3: Role of Electron-Phonon Coupling
M. V. Costache, I. Neumann, J. F. Sierra +4
We report on electric-field and temperature dependent transport measurements in exfoliated thin crystals of BiSe topological insulator. At low temperatures ( K) a…
