Abstract

Zinc mercury thiocyanate (ZMTC) is an organometallicnonlinearly optical (NLO) single crystal that has been grown in an aqueous solution using the SR technique. Novel, non-destructive method is suggested and shown to enhance the electrical properties of crystals through the use of shock waves. A tabletop shock tube, operating at a Mach number of 1.7, generates shock waves that are subsequently loaded into a zinc mercury thiocyanate (ZMTC) crystal. This process, driven by pressure, induces changes in the dielectric characteristics of the crystal. The shock waves are initiated perpendicular to the (1 1 0) plane of the crystal. The electrical properties, including dielectric constant, dielectric loss, AC conductivity, and activation energy of the ZMTC crystal, were examined across a frequency spectrum ranging from 4 Hz to 8 MHz. The analysis encompasses both with and without shock wave loaded conditions.The results of the experiments show that the dielectric constant of ZMTC crystal is prone to respond to shockwaves, with the rate increasing for the with shock wave loaded ZMTC sample. The suggested approach offers a viable alternative to traditional doping methods for customizing the dielectric characteristics of crystals in the ZMTC family.
