In-gap state and effect of light illumination in CuIr${}_2$S${}_4$ probed by photoemission spectroscopy

K. Takubo, T. Mizokawa, N. Matsumoto +1

We have studied disorder-induced in-gap states and effect of light illumination in the insulating phase of spinel-type CuIr${}_2$S${}_4$ using ultra-violet photoemission spectroscopy (…
