1. A field-emission device, comprising a solid state structure formed of a crystalline material which comprises a plurality of crystalline nanostructures and an amorphous material, wherein an outer surface of said solid state structure comprises a portion of said crystalline nanostructures and is substantially devoid of said amorphous material, and wherein a p-type conductivity of said crystalline material is higher at said outer surface which is substantially devoid of said amorphous material than far from said outer surface which is substantially devoid of said amorphous material, and wherein said portion of said crystalline nanostructures protrude outwardly from said amorphous material.
