Correlation of domain structure of TGS single crystals doped with serine and its dielectric properties: new constructed computer measuring system for quantity analysis of domain images

This paper presents work over correlation between parameters of domain structure and pyroelectric current in IR sensors based on TGS. In the frames of realized works new single- crystal of TGS doped with amino acid-serine was grown. Computer measuring system making possible registration of domain structure images of non-linear dielectrics was designed and executed. We worked out measuring and analysis algorithms of domain images. Software making possible calculations and analysis of parameters of observed structures was created and static measurements of domain structure within different growth pyramids were performed. Correlation between parameters of domain structure, quantity of admixture and temperature characteristics of pyroelectric coefficient was found.
