ABSTRACT:
A temperature sensor comprises a body of insulating diamond material and a pair of spaced apart electrical contacts applied to the body. The body has a predetermined thickness between the contacts, and the contacts have a predetermined area, so that the sensor has a corresponding capacitance between the contacts which is temperature dependent The diamond body may comprise a diamond crystal, or may be a layer of diamond deposited on a substrate by a CVD process. In the latter ease, the substrate may be a semi-conductive silicon layer, which serves as one of the contacts. The other contact may be a metallic contact, or may comprise a layer of doped amorphous semi-conductive material. The sensor is sensitive to ionizing radiation as well as to changes in temperature, and is suitable for use in a temperature compensated radiation measuring apparatus.
