- Abstract
We report on the low-temperature study of thick YSi films that are of potential interest for applications in low-temperature thermometry. Thick amorphous Y x S i 1 - x films (300 to 600 Å) have been synthesized, and the temperature variation in their resistance is studied as a function of the stoichiometry of the alloy. These measurements show that Y x S i 1 - x can exist in various states: insulating, metallic and superconducting. We have determined a preliminary phase diagram for the 3D Y x S i 1 - x alloy. On the superconducting side, the Y 30 S i 70 film shows a sharp transition at about 1K. This superconducting compound therefore is a promising candidate for transition-edge sensors.
