The authors report on the experimental observation of strongly nonequilibrium solitary formations, i.e. hot autosolitons (AS), in the stable, weakly nonequilibrium electron-hole plasma that was uniformly photogenerated in Ge samples at 77 K and slightly heated by an applied electric field. AS revealed themselves as narrow strata, perpendicular to the lines of current and moving along them without attenuation, which were distinguished by a lowered concentration of carriers and increased strength of electric field.
