G. Schmidt, L.W. Molenkamp A loadline method for determining the efficiency of spin injection contacts Semicond. Sci. Tech. 19 (2015-02-24 16:09:55), 1161-1164
Spin aligners and spin filters are necessary ingredients for spintronic devices. While the principle of operation is now well understood for a variety of spin filters, we point out that the efficiency of a given type of injector as to spin selectivity depends drastically on the actual device or circuit in which it is used. We present an approach based on loadlines that can be used to determine the spin injection efficiency of spin aligners and spin filters in combination with complex loads. http://iopscience.iop.org/0268-1242/19/9/016/ |
