The unusual thickness dependence of superconductivity in $\alpha$-MoGe thin films

H. Tashiro, J. M. Graybeal, D. B. Tanner +3

Thin films of $\alpha$-MoGe show progressively reduced $T_c$'s as the thickness is decreased below 30 nm and the sheet resistance exceeds 100 $\Omega /\square$. We have performed far-infrared…
