Cristais orgânicos
Efeito eletroóptico
Interferômetro
Abstract in Portuguese
Este trabalho trata da caracterização eletroóptica de cristais orgânicos, a saber: L-arginina fosfatada, L-alanina e L-treonina. O aspecto teórico que envolve este efeito nestes cristais é descrito, discutindo a forma de manifestação do efeito em cada um dos grupos de simetria cristalina aos quais pertencem. Além disso, discutimos e observamos a ocorrência de efeitos de natureza piezoelétrica durante o processo de caracterização eletroóptica.

Organic crystals
Abstract in English
This work reports on the electrooptical characterization of organic crystals, namely: L-arginine phosphate monohidrate, Lalanine and L-threonine. We describe the theoretical aspect in these crystals discussing how the effect occurs according to the symmetry groups of each one. Furthermore, we discuss and observe the occurrence of piezoelectric effects during the electrooptical characterization.
