Temperature dependence of field emission of nano-diamond
纳米金刚石的变温场发射

The field emission characteristics of nano-diamond deposited on titanium substrate at various temperatures are studied.It was found that the emission current increases with increase of temperature and electric field,while the stability of the emission current basically does not change.The field emission characteristic deviates from classic Fowler-Nordheim theory.The mechanism of the emission current at different temperatures is analyzed.It may be due to the combined action of scale effect of the nano-diamon...
