Investigation on crystallinity, stability and piezoelectricity of l-arginine 4-nitrophenolate 4-nitrophenol dihydrate single crystal

l-Arginine 4-nitrophenolate 4-nitrophenol dihydrate single crystals have been grown from slow evaporation solution growth technique. Crystalline perfection of the crystal has been evaluated by high resolution X-ray diffraction technique and it reveals that the crystal quality is good and free from structural grain boundaries. Mechanical stability of the crystal has been analyzed by Vickers microhardness measurement and it exhibits reverse indentation size effect. The surface laser damage threshold for the crystal has been analyzed and its value is 0.504 GW/cm2. Piezoelectric d33 co-efficient for the crystal has been examined and its value is 18 pC/N.
