Investigating the Influence of Shock Waves on the Dielectric Characteristics of ZMTC Crystals
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, …
