Abstract

It is established experimentally that a high concentration of electron-hole plasma produced in silicon by femtosecond laser pulse induces a sequential “collapse” of the band gap in the [111] and [100] directions and leads to the formation of a “cold” metallic liquid phase during the pulse.
