Effect of a temperature gradient on the polarization distribution in the surface layer of TGS crystals

Effect of variable temperature gradients on the polarization of the surface layers of triglycine-sulphate (TGS) crystals has been analyzed. A fundamental difference in the impact of these gradients on the sample sides corresponding to the positive (“+” P _s ) and negative (“?” P _s ) yield of the polarization vector has been discovered. In particular, it has been found that repolarization of the surface layer under the impact of thermal radiation occurs only on the “?” P _s side.
