Crystallization temperature predictions in phase-change materials using a novel approach

Abstract

A crucial factor affecting chalcogenide materials’ thermal stability and phase transformation behaviour is their crystallization temperature (T<inf>c</inf>), which is motivated by iso-conversional analysis. In this study, we present a novel correlation for predicting T<inf>c</inf>. The theoretical estimate of T<inf>c</inf> provided by the recently developed correlation perfectly matches the values derived from Differential Scanning Calorimetry (DSC) measurements. This agreement demonstrates the precision and dependability of our method for figuring out the kinetics of the crystallization of chalcogenide materials. Our correlation provides a reliable approach for accurate T<inf>c</inf> prediction by integrating theoretical and experimental analyses, advancing phase-change materials and their uses. The suggested model enhances our understanding of crystallization dynamics and is a valuable tool for material optimization and design. The crystallization activation energy calculated using our correlation maintains a constant difference from the activation energy obtained through the Various Heating Rate (VHR) method. This study underscores the significance of the proposed method as a powerful tool in crystallization studies, particularly for materials where accurate determination of crystallization temperature is crucial. The observed constancy in the activation energy difference further validates the robustness of this approach. © 2025
