Sažetak
Temperature invariance of the Urbach energy and parallel red shift of optical absorption edge in the incommensurate phase of Sn2Р2Se6 ferroelectric is analyzed. The observed effect is explained by the presence of dynamic structural disordering of the crystal lattice caused by a wave of structure modulation which is formed by the shift of tin atoms.
