A fingerprint for free carbon was identified from the negative ion mass spectra of various carbon and silicon carbide standards. It was found that high‐mass carbon molecular species can be used to distinguish free carbon in silicon carbide. Seconda

Little is known of the composition of the neutral particle fluxes released during the electrical breakdown of insulating films in vacuum. Analysis of the released particles is unusually difficult because of the transient nature of the event, the unpr
