Annotation

The temperature dependence of electrical conduction was studied and the activation energy was calculated for crystals with long hydrogen bonds, viz., lithium, yttrium, holmium, and erbium formates, urea and thiourea. A weak pyroelectric effect was revealed in the urea crystal at a temperature below room temperature. At temperatures below the phase transition temperature ($Т_С$ = 169 K) in weak electric fields, the thiourea crystal showed anomalies associated with a change in the behavior of protons on hydrogen bonds.
