Metal-insulator transition upon heating and negative-differential-resistive-switching induced by self-heating in BaCo0.9Ni0.1S1.8

B. Fisher, J. Genossar, K. B. Chashka +2

The layered compound BaCo1-xNixS2-y (0.05<x<0.2 and 0.05<y<0.2) exhibits an unusual first-order structural and electronic phase transition from a low-T monoclinic paramagnetic meta…
