摘要：
By applying nonequilibrium Green's functions in combination with density-function theory, the spin-dependent transport properties of cross-linked carbon nanotube spintronic devices are investigated. Our calculations show that the perfect spin filtering effect with the almost 100% spin polarization, and the magnetoresistance effect with a magnetoresistance ratio larger than 10 4% can be observed in the device. The occurrence of the perfect spin-filtering and magnetoresistance effects in the cross-linked carbon nanotube spintronic device provides...
