Pyroelectric properties of the modified triglycine sulphate (TGS) single crystals

Abstract
Several doping substitutions (Li+, Mn+, D+, P+5, As+5) in the TGS structure have been studied and the pyroelectric and dielectric properties measured. In the case of TGS single crystals modified by partial substitution of (P04 −3 and (As04)−3 groups for the (S04)−2. higher pyroelectric coefficients and an enhancement of the pyroelectric material figure of merit (p/K) > 2 x TGS have been observed.
