Influence of growth and annealing conditions on low-frequency magnetic 1/f noise in MgO magnetic tunnel junctions
(2012)Magnetic 1/fnoise is compared in magnetic tunnel junctions with electron-beam evaporated and sputtered MgO tunnel barriers in the annealing temperature range 350 - 425??C. The variation of the magnetic noise parameter (? ... -
Nonequilibrium Green's function study of Pd4-cluster-functionalized carbon nanotubes as hydrogen sensors
(2009)Pd-cluster-functionalized carbon nanotubes CNTs have been shown experimentally to be effective hydro- gen sensors. Semiconducting CNTs exhibit much higher sensitivity than ensemble mixed ones. Using the nonequilibrium ... -
Origami-based spintronics in graphene
(2013)We show that periodically folded graphene sheets with enhanced spin-orbit interaction due to curvature effects can carry spin-polarized currents and have gaps in the electronic spectrum in the presence of weak magnetic ...
