To tailor electrical properties of often degenerate pristine CuI, Ni is introduced as alloy constituent. Cosputtering in a reactive, but also in an inert atmosphere as well as pulsed laser deposition (PLD), is used to grow Ni x Cu 1 − x I $\left(\text{Ni}\right)_{x} \left(\text{Cu}\right)_{1 - x} \text{I}$…
