Abstract
The appearance or initial existence of microtips on the cathode surface is one of the main reasons of prebreakdown field emission (FE) current. Thermal explosion of these tips lead to explosive electron emission and initiating of vacuum breakdown. In the last years the sufficient role of super small tips (10-6 - 10-7 cm) in prebreakdown phenomena and initiating vacuum breakdown was established. The amplification of electric fields on such tips leads to very high FE current densities (J > 10+9 A/cm2). So, the creation and decay of nanometer structures define the dynamics of the vacuum breakdown development. The investigations of FE from nanometer formations are very actual, as the emission properties and stability of such structures are connected with the problems of field cathodes fabrication and exploitation in the devices of vacuum micro- and nanoelectronics. In this report the results of preliminary investigation of high current densities FE from nano-emitters are presented.
