| Popis: | Resistance-based thermometry is a simple and widely used technique, though we still lack a single sensor that spans a broad temperature range without losing sensitivity. This article presents an alloy that is useful for thermometry from room temperature down to about 100 mK with little variation in its dimensionless sensitivity. Its resistivity varies logarithmically from approximately 200 K down to approximately 200 mK, allowing for simple calibration, and it can be patterned on a chip alongside experimental devices. This material might be quite useful in producing a chip-integrated thermometer operating at stable sensitivity over three decades in temperature. |
