ABSTRACT:
Continual boron-doped diamond parts with ends are formed in a non-doped insulating diamond crystal. Ohmic electrodes are deposited on the ends of the boron-doped diamond parts. Non-doped diamond encloses and insulates the boron-doped diamond parts. When the boron-doped diamond parts are supplied with a current, the boron-doped diamond parts generate Joule's heat. The device acts as a heater. Since the whole heater is made of diamond crystal, the heater can posses an extremely small size. The heater enjoys high resistance against high temperature, especially in an anaerobic atmosphere. The diamond heater can be adopted in vacuum or in liquid, since the insulating diamond layers are highly resistant against vacuum and liquid.
