A diamond thermistor is described. Surface portions of temperature sensing diamond of the thermistor are doped with impurity ions by ion implantation except for a sensing area thereof. A pair of electrodes are formed on the impurity regions in order to make good ohmic contacts with the diamond. The damage...http://www.google.se/patents/US5089802?utm_source=gb-gplus-sharePatent US5089802 - Diamond thermistor and manufacturing method for the same
