A systematic search is made for semiconductor models displaying non-equilibrium phase transitions induced by recombination and generation processes. Formal conditions are elaborated for some typical classes of reaction kinetic models with a phase transition. Under this aspect various recombination and generation mechanisms involving electrons, holes and traps are surveyed systematically, and subsequently two new classes of band–trap models exhibiting first and second order phase transitions, respectively, are constructed.
