Abstract
A new thermistor working within a wide temperature range is presented. Processing techniques and thermal and electrical characteristics are described. The sensing element is ``pure'' crystal-line boron, and the contacts, performed through a nickel-boron alloy, allow the device to hold up to 990°C. The very high sensitivity, the stability over a wide temperature range, and the reproducibility all make the sensor both suitable for temperature measurements and promising in a wide field of applications.
