Field emission characteristics of diamond films with different surface morphologies

In recent years, field emission from diamond films has attracted a lot of attention because of the excellent physical and chemical properties of diamond. The emission property of diamond is influenced by defect, doping and surface state et al, surface state of diamond is very important aspect. In this work, we carried out an experiment and analytical study of field emission from diamond with various crystal grain size and orientation produced by chemical vapor deposition (CVD).
