Studies on Mechanical and Dielectric Properties of L-Phenylalanine Benzoic Acid Single Crystal for NLO Applications

Nonlinear optics (NLO) materials have a significant impact on laser technology, optical communication, optical storage technology, and electrooptic modulation. Nonlinear optical single crystal of L-phenylalanine benzoic acid has been grown by slow evaporation. The XRD analysis confirms that the crystal belongs to the monoclinic system with noncentrosymmetric space group P21. Microhardness investigations are conducted on the grown crystals. The dielectric response of the sample is studied as a function of different frequencies and different temperatures. The photoconducting studies confirm that the title compound has negative photoconducting nature.
