Pyroelectric activity in non-centrosymmetric Langmuir-Blodgett multilayer films
GW Smith, MF Daniel, JW Barton, N Ratcliffe - Thin Solid Films, 1985 - Elsevier
We report the detection of pyroelectric activity in non-centrosymmetric Langmuir-Blodgett
multilayer films of structure ABAB… where A and B are monolayers of different materials.
Films consisting of alternating fatty amine and fatty acid layers give a pyroelectric coefficient
p of approximately 5× 10− 11 C cm− 2 K− 1, about three orders of magnitude less than for
high performance pyroelectrics. In an attempt to produce improved pyroelectric coefficients a
surface-active derivative of a highly polar chromophore has been synthesized and …
