Abstract
Previous work employed X-ray three-beam diffraction techniques to obtain
part of the L-arginine hydrochloride monohydrate (L-AHCL. H2O)
piezoelectric coefficients, namely d(21), d(22), d(23) and d(25). Those
coefficients were obtained by measuring the shift in the angular
position of a number of secondary reflections as a function of the
electric field applied in the 010 piezoelectric direction. In this
paper a similar procedure has been used to measure the remaining four
piezoelectric coefficients in L-AHCL. H2O: with the electric field
applied in the 100 direction, d(14) and d(16) were measured; with
the electric field applied in the 001 direction, d(34) and d(36)
were obtained. Therefore the entire piezoelectric matrix of the L-AHCL.
H2O crystal has been successfully measured.
