The possibility of growing of the solid solution (Si2)1 - x - y (Ge2)x (ZnSe)y on silicon substrates by liquid-phase epitaxy from the tin solution - melt has been shown. The current - voltage characteristics of heterostructures at room temperature has three sections: ohmic section - I ~ V , exponential one - I ~ exp ( qV / ckT ), and the third one with cubic dependence - I ~ V3 that at increasingtemperature is replaced by the weaker dependences - I ~ V2,8, I ~ V2,5 and I ~ V2,3 at temperatures of 360, 390 and 420 K, respectively. The experimental results are explained on the basis of theoretical ideas about the complex nature of the recombination processesin these materials.
