Electron-hole drops and the appearance of a strong plasma in Ge at a high level of optical excitation
Ashkinadze B.M., Fishman I.M.
At a high level of excitation of germanium, regions were observed of a dense electron-hole plasma, accompanied by the appearance of fast kinetics of the decrease of the recombination radiation of the electron-hole drops. These results are explained as being the consequence of the effect of the dispersal of the drops when a certain threshold excitation level is reached, when the kinetic energy of the rapidly moving drops turns out to be sufficient to break up the drop by inelastic impact and produce a cluster of dense plasma.
