Abstract
•Thiourea cadmium iodide (TCI) was grown by slow evaporation solution technique.•Morphology and growth rate of the grown compound are determined with the help of inverted microscope.•Optical band gap has been determined.•Microstructure analysis has been reported.•Electrical study has been reported and discussed.
In this work, the single crystals of thiourea cadmium iodide were grown by slow evaporation solution technique in two different ratios 2:1 and 1:1. During the formation of their single crystals the morphological features and its live growth process were recorded with the help of inverted microscope. Structural studies of the grown crystals have been carried out by powder X-ray diffraction to confirm the crystal system and vibrational modes by Raman spectroscopy. The optical energy band gaps were investigated through UV–vis spectroscopy study. The surface morphology of the grown single crystals was analyzed by using Scanning Electron Microscope and thermal analysis was carried out by using thermogravimetric analysis. The electrical properties were also studied as a function of frequency and the obtained results are discussed.
