Growth, mechanical, dielectric and photoconducting properties of thiourea added L-histidine crystals (TLH)

Single crystals of Thiourea added L-histidine (TLH) has been grown by slow evaporation solution growth technique. The unit cell parameter of the as grown crystal was determined by single crystal X-ray diffraction technique. The grown crystal was subjected to mechanical studies. Vicker’s Microhardness studies indicate that the grown crystal is soft in nature. Dielectric loss and dielectric constant measurements were carried out at different temperatures and frequencies. The photoconductivity studies confirm that the title compound has positive photoconducting nature.
