Abstract

The main products, sulfur dimers (S2), sulfur atoms (S) and cadmium atoms (Cd), ejected from highly excited CdS, show Maxwellian velocity distributions characterized by an unusually low kinetic temperature, indicating that the laser induced damage of CdS in high-density electron-hole plasma does not undergo a thermal melting, but a direct solid-gas phase transition driven by dimerization of adjacent sulfur atoms.
