By using a focused-ion-beam (FIB) method with Ga ions, we prepared quasi-one-
dimensional (q-1D) In/Mo specimens with widths of≈ 200 nm and≈ 500 nm from two
dimensional (2D) films deposited on a SiO 2/Si substrate. We observed the superconducting
transition of q-1D In/Mo, whose transition temperature T c is higher than T c≈ 3.6 K of a 2D
In/Mo specimen on a glass substrate. For specimens fabricated using the FIB method, the
element distributions analyzed by energy dispersive x-ray spectroscopy reveal Ga invasion …
