Vacuum microelectronics research hotspot collar city, and has been rocking on the field emission flat panel display applications

Diamond has many excellent properties especially, such as high hardness, high thermal conductivity, high chemical stability foot, etc., in the electrical performance, because it unique "negative electron affinity", it has a low work function, thus mention that the ideal field emission cathode material in recent years become a leading city of synthetic diamond powder research hotspot, and has been rocking on the field emission flat panel display applications for mattress; but most researchers in plasma  synthetic diamond deposition of polycrystalline diamond films for the study, the field emission characteristics are not satisfactory, mainly the presence of the starting field emission high emission current density is small.
