Abstract

The influence of pH of solution on growth rates of the faces (001), (010), (100) and habit of TGS and TGSe single crystals was studied. The pH‐values were determined when growth of TGS and TGSe crystals was ceased. At pH < 1 diglycine sulphate (DGS) and at pH < 2 diglycine selenate (DGSe) crystals are growing. The permittivity and resistivity of DGS and DGSe were measured. The resistivity of DGSe is an order of magnitude less than of TGSe for the same temperature. The possible mechanism of change of crystal morfology vs pH, supersaturation of solution and growth temperature is proposed.
