【Abstract】 The high-resistance region in Tin Oxide film acts as a cold electron source with noncollimated electron output current of the order of 100-200 uA.. The primary experimental results show that the high-resistance region with the capability of electron emission has a change in composition, and the energy distribution of the emitted electrons is different from that of the field emission. The magnitude of the electron current is influenced by both the gaseous component and the pressure in the test chamber.更多还原
