Paper Abstract

The paper reports a systematic microscopic analysis of metallic surface defects which are in a position to determine the breakdown threshold of a gas in close vicinity of a target surface. Metallic and nonmetallic defects with a vaporization threshold lower than that of an ideal flat metal surface were evidenced which are able to cause the lowering of the gas breakdown threshold in the neighbourhood of the metallic target.
