| Abstract: | The experimental studies of hydrostatic pressure effect upon fundamental optical absorption spectra in Sn(Pb)2P2S(Se)6 mixed crystals of different composition are carried out. The increase of Pb content in (PbySn1-y)2P2S6, (PbySn)2P2Se6 crystals is shown to result in the enhancement of electron-phonon interaction and to the reduction of the energy gap deformation potential Dg. Isomorphous substitution of S by Se in the Sn2P2(SxS1-x)6 solid solution row does not affect significantly the electron-phonon interaction value and Dg. |
