Investigations of photo-transient properties and applications as photosensors in well-characterized tin telluride (SnTe) single crystal

Abstract

The current scenario demands new semiconducting materials for the development of fast-reacting sensors, detectors, and special solid-state devices. On the way to finding a solution, alloy engineering has emerged as a vital option for the research community. The present study focuses on the investigation of photo-transient properties and the potential application of a well-characterised Tin Telluride (SnTe) single crystal as a photo-sensor. SnTe has attracted significant attention due to its promising optoelectronic properties and its large suitability for a variety of applications in various fields of material engineering. The present work employs various characterizations/.vm, dmjmof grown single crystals to understand their structural, morphological, and electrical properties. Furthermore, the photo-transient properties of SnTe were investigated by an in-house design setup to study its photo-driven reaction under different illumination conditions. The results reveal the excellent photo-response of the fitted sample, suggesting a fast response time, high sensitivity, and wide spectral reacting ability of the grown crystalline material. Additionally, we explore the feasibility of SnTe as a photosensor by investigating its performance under environmental conditions. The findings indicate that SnTe exhibits remarkable stability and reliability, making it a promising candidate for photo-sensing applications. The insights obtained from this investigation contribute to the understanding of the photo-transient behaviour of SnTe and provide valuable knowledge of optical and photo-responsive parameters for designing efficient photosensors using grown material.
