Nano-diamond ridge structure emission arrays capped on micro-patterned silicon pillars

CVD nano-diamond structures are interesting electron emitters because of their superior electronic properties and tolerance to operate at much higher temperatures and harsh environments. Other advantages of nano-diamond as emitters include chemical and electrical stability, high breakdown voltage, low turn-on electric field and excellent thermal conductivity. In this paper, the authors report the fabrication and observation of electron field emission from an array nano-diamond ridge structure capped on micropatterned silicon pillars.
