摘要：
The MNDO calculation method and molecular cluster model are used to study the influence of substitution defects formed by alkali metal (Li, Na, K) and halogen (Cl, I) atoms on the saturation polarization and forbidden gap of polyvinylidene fluoride (CH22CF2) a pyroelectric with pronounced photoelectric properties. Densities of state are calculated for both the defectless pyroelectric and for the sample with substitution defects. The calculated energy characteristics are in good agreement with the available experimental data.
