Abstract

The picosecond relaxation of an electronically excited insulator is described by means of an extension of the two-temperature model. In this phenomenological description, charge neutrality is enforced, but the electron and hole chemical potentials are not forced to be equal. Different experimental regimes can be characterized by comparing the electron-lattice and electron-hole relaxation rates. The dependency of the long-time relaxation on both the electronic gap and the sample density is discussed. The extend two-temperature model correctly describes the unexpectedly long transient opacity displayed by a borosilicate glass irradiated by ultrafast proton pulses.
