Longitudinal and Transverse Pyroelectric Effects in a Chiral Ferroelectric Liquid Crystal

Artículo de publicación ISIIn this study, we compare the results of experimental investigations of longitudinal and transverse pyroelectric effects in a chiral ferroelectric crystal. In a transverse geometry, we studied freely suspended liquid-crystal films. In both geometries, samples exhibited bistability, demonstrating stable pyroelectric signals of different polarities at zero voltage. It is shown that a bistable cell based on a freely suspended film requires 40 times less energy expenditures as compared to the conventional sandwich-type cell.Russian Science Foundation (project no. 14 12 00475); Soto Bustamante and Romero Hasler express their sincere gratitude to Fondecyt 1130187
