Observing and Suppressing Metallization in MoS₂ for Near-Ideal Spin Filtering.

ABSTRACT: Two-dimensional (2D) transition-metal dichalcogenides (TMDCs) offer band alignments that are well-suited for minority-spin filtering when interfaced with ferromagnets. Unfortunately, interfacial hybridization results in the emergence of metallic states in MoS₂ that have limited previous results significantly below theoretical expectations. Here, we study the metallization at the Co/MoS₂ interface and devise a method to overcome its detrimental impact on spin transport. Using a contamination-free fabrication process, clear evidence of hybridization was observed, which increases the magnetic anisotropy of the interface. Magneto-transport and theoretical analysis reveal that the metallic wave functions extend into the MoS₂ layer, suppressing its ability as a f
