Tunable conductive mechanism for realizing spin-selective charge carrier transport in thin- film WSe2 for compact/ efficient spintronic devices

"control over how electrons with different spin orientations move through material using external magnetic or electric fields... no need to integrate different materials into complicated structures... spin-selective transport using single, non-magnetic WSe2... spin selectivity due to contrast in electrical conductivity, depending on mobile carriers' spin at Fermi level: highly tunable when mobile carriers have different spin from background causing stall, but when spins match, Pauli exclusion prevents strong interaction"
