Polarization amplification by spin-doping in nanomagnetic/graphene hybrid systems
نویسندگان
چکیده
The generation of nonequilibrium electron spin polarization, transport, and detection are fundamental in many quantum devices. We demonstrate that a lattice magnetic nanodots enhances the polarization monolayer graphene via carrier exchange. probed through resistively detected variant resonance observed amplification mediated by presence nanodots. Each nanodot locally injects surplus spin-polarized carriers into graphene, ensemble all hot spots generates layer at macroscopic lengths. This occurs whenever interdot distance is comparable or smaller than diffusion length.

متن کاملHybrid topological-spin qubit systems for two-qubit-spin gates
We investigate a hybrid quantum system involving spin qubits, based on the spins of electrons confined in quantum dots, and topological qubits, based on Majorana fermions. In such a system, gated control of the charge on the quantum dots allows transfer of quantum information between the spin and topological qubits, and the topological system can be used to facilitate transfer of spin qubits be...
متن کاملFormation of molecular doping patterns in organic-inorganic hybrid films by a capillary electrophoresis doping technique.
A new technique is proposed for the fabrication of fine patterns of molecular doping in organic-inorganic hybrid materials by the combination of capillary electrophoresis doping (CED) and photolithography. The UV-induced polymerization of [Formula: see text] bonds in organic groups yields a fine contrast of structures with the desired pattern in organic-inorganic hybrid films, and CED treatment...
