Curvature-enhanced Spin-orbit Coupling and Spinterface Effect in Fullerene-based Spin Valves
We investigated curvature-enhanced spin-orbit coupling (SOC) and spinterface effect in carbon-based organic spin valves (OSVs) using buckyball C60 and C70 molecules. Since the naturally abundant (12)C has spinless nuclear, the materials have negligible hyperfine interaction (HFI) and the same intrinsic SOC, but different curvature SOC due to their distinct curvatures. We fitted the thickness de...
متن کاملLarge spin-orbit coupling in carbon nanotubes.
It has recently been recognised that the strong spin-orbit interaction present in solids can lead to new phenomena, such as materials with non-trivial topological order. Although the atomic spin-orbit coupling in carbon is weak, the spin-orbit coupling in carbon nanotubes can be significant due to their curved surface. Previous works have reported spin-orbit couplings in reasonable agreement wi...

متن کاملRashba Spin−Orbit Coupling Enhanced Carrier Lifetime in CH3NH3PbI3
Organometal halide perovskites are promising solar-cell materials for next-generation photovoltaic applications. The long carrier lifetime and diffusion length of these materials make them very attractive for use in light absorbers and carrier transporters. While these aspects of organometal halide perovskites have attracted the most attention, the consequences of the Rashba effect, driven by s...
متن کاملGate-dependent spin–orbit coupling in multielectron carbon nanotubes
We here present additional theoretical analysis and experimental data supporting the conclusions in the article. First, the carbon nanotube dispersion relation including spin-orbit interaction is reviewed starting from a modified Dirac Hamiltonian, and the single-particle model used in the fitting procedure is explained. Second, tunneling spectroscopy data and the corresponding analysis used to...
