Investigation of structural, mechanical, dielectric, and thermal behaviour of pure and L-H doped LSMH single crystals

Abstract

Lithium Sulphate Monohydrate (LSMH) and L-histidine amino acid doped Lithium Sulphate Monohydrate single crystals in a conjugate solution were grown using a slow evaporation process. The mechanical properties, thermal stability, and dielectric properties have all been confirmed by using various characterization techniques. Powder X-Ray diffraction studies were used to examine the space group and its lattice parameters, and the results showed that both crystals were arranged in a monoclinic system that was non-Centro symmetric and had the space group P21. Functional groups that were present in the grown samples were explained in great detail by Fourier Transform Infrared Spectroscopy. EDAX analysis was used to identify the measurements of the various elements that were present in the crystal sample of Lithium Sulphate Monohydrate doped with L-histidine amino acid. A Vickers micro hardness analyzer was used to determine the crystals' hardness characteristics. In-depth explanations were provided for the thermal stability of the samples, which was determined by TG/DTA analysis. The electrical behaviour of the pure LSMH and L-Histidine-doped LSMH crystal was observed using the LCRZ metre.
