Originální abstrakt

The paper introduces a method for deposition thick oxide layer on to the cold emission cathode and its noise diagnostics. Cathodes based on the Schottky emission are predominant electron source technology for scanning electron microscopy (SEM), transmission electron microscopy (TEM) and Auger systems. Achieving proper results requires an electron source with the following ideal properties: small source size, low electron emission energy spread, high brightness, low noise and long-term stability, simple and low-cost operation. Deposited oxide layer allows to significantly lower work function, which is necessary for increasing cold electron emission current.
