a Optical image of SL-MoSe₂ flake on top of the hole. b Junction resistance of SL-MoSe₂ at different temperatures. (Inset) Temperature-dependent I-V curves of vertical Co/SL-MoSe₂/NiFe SVJ demonstrates a metallic junction. c The variation of R vs B at T = 300, 200, 100, 50, and 4 K before annealing. d The temperature-dependent MR ratio of Co/SL-MoSe₂/NiFe before and after annealing at fixed current.
