2. High-voltage vacuum cladding

Breakdown occurs when the voltage exceeds a certain threshold value U c known as the breakdown voltage. Above U c , a significant electric current is established between the electrodes, i.e. an electric discharge [D 2 830][D 320] . The voltage U c depends not only on the shape, but also on the nature of the material making up the electron-emitting surface, the electrode itself. At the microscopic level of...
