Recombination radiation in p-ZnSnP2 single crystals

We have carried out complex investigations into the recombination radiation of p-ZnSnP₂ single crystals produced by methods involving recrystallization from nonstoichiometric melts with cooling at a controlled rate (type-I crystals) and under steady-state conditions (type-II crystals). We discuss the effect of crystal-growth conditions on the spectral contour and the position of the band maxima for recombination radiation. Type-II crystals exhibit edge exhibition and it is demonstrated that the shift of the long-wave bands in type-I crystals is controlled by the rate of cooling. The nature of the observed radiation transitions is discussed.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 4, pp. 43–48, April, 1986.
