Latest Patents

Efremow holds 2 patents related to field emitters of wide-bandgap materials. His latest patents focus on improved field-emission devices that enhance electron-injection efficiency into the emitter material. This is achieved by altering the structure of the emitter material near the contact or through geometric field enhancement due to contact morphology. The devices he has developed are capable of emitting electrons at high current densities and lower applied potential differences and temperatures than previously achieved. Notably, wide-bandgap emitter materials without shallow donors benefit from this innovative approach. The emission characteristics of diamond, which is substitutionally doped with nitrogen, show significant improvement in the context of his inventions. The injection-enhancing contacts can be created by combining the emitter material with an appropriate metal compound and annealing or by using conventional dry anisotropic etching or ion bombardment techniques.
