Abstract
We present the first measurements of time-resolved luminescence spectra during the growth of electron-hole liquid in Si excited by 15-nsec optical pulses. The results clearly show that at high excitation intensities, the electron-hole liquid forms directly from a hot, dense plasma rather than from a gas of excitions.Keywords
