Abstract
The hypothesis is put forward on the basis of experimental data that strong inhomogeneous heating of the skin layer of conducting materials by a femto second pulse gives rise to a double electrical layer that is formed of a "s urface" layer of positive ions and a thin (about 1 nm) "subsurface" layer o f a superdense (10(23)-10(25) cm(-3)) degenerate electron gas. The double l ayer breaks within one picosecond through the Coulomb explosion. (C) 2001 M AIK "Nauka/ Interperiodica".
