(author)We report measured T<sub>c</sub> of superconducting Ti/Au bilayer strips with a width W varying from 5 to 50 µm. The strips were fabricated based on a Ti/Au bilayer that consists of a 41-nm-thick Ti layer to which a 280-nm-thick Au layer was added. We find that the T<sub>c</sub> drops as W decreases and the declining trend almost perfectly...journal article 2022
