摘要

摘要硫系玻璃因其相变特性而成为目前最受欢迎的材料之一。相变材料(PCM)在光子学、存储器件、成像等领域有着重要的作用。为了研究三元Sb10Se90-xGex (x = 0, 19, 21, 23, 25, 27)和四元Sb10Se65Ge25-yIny (y = 0, 3, 6, 9, 12, 15)硫族化合物体系作为PCM的价值，探讨了掺杂剂的组成变化及其对两种体系热性能的影响。利用S参数、脆性指数、玻璃化转变温度和结晶温度下的速率常数等标准研究了两种玻璃体系的热稳定性。利用Avrami指数研究了玻璃中发生相变现象的机理。关键词:硫属化合物热稳定性avrami指数结晶披露声明作者未报告潜在利益冲突。数据可用性声明本文无相关数据，否则数据将不予保存。[作者评注:相关数据和结果已在图和表中显示/报道]

A study of the crystallization kinetics of Sb-Se-Ge and Sb-Se-Ge-In chalcogenide glasses for applications as phase change materials

ABSTRACTChalcogenide glasses are unquestionably one of the most popular materials known for their phase change property. Phase change materials (PCM) have a key role in the field of photonics, memory devices, imaging, etc. With an aim to study the worth of ternary Sb10Se90-xGex (x = 0, 19, 21, 23, 25, 27) and quaternary Sb10Se65Ge25-yIny (y = 0, 3, 6, 9, 12, 15) chalcogenide systems as PCM, the composition variation and effect of dopants on the thermal properties of two systems has been probed. The thermal stability of two glass systems has been investigated using criteria such as the S parameter, fragility index, and rate constants at glass transition and crystallization temperatures. The mechanism of the phase change phenomenon occurring in the glasses has been studied using the Avrami index.KEYWORDS: Chalcogenidesthermal stabilityAvrami exponentcrystallization Disclosure statementNo potential conflict of interest was reported by the author(s).Data availability statementThis manuscript has no associated data, or the data will not be deposited. [Authors’ comment: The related data and results obtained have been shown/reported in the figures and tables.]

期刊介绍： Phase Transitions is the only journal devoted exclusively to this important subject. It provides a focus for papers on most aspects of phase transitions in condensed matter. Although emphasis is placed primarily on experimental work, theoretical papers are welcome if they have some bearing on experimental results. The areas of interest include: -structural phase transitions (ferroelectric, ferroelastic, multiferroic, order-disorder, Jahn-Teller, etc.) under a range of external parameters (temperature, pressure, strain, electric/magnetic fields, etc.) -geophysical phase transitions -metal-insulator phase transitions -superconducting and superfluid transitions -magnetic phase transitions -critical phenomena and physical properties at phase transitions -liquid crystals -technological applications of phase transitions -quantum phase transitions Phase Transitions publishes both research papers and invited articles devoted to special topics. Major review papers are particularly welcome. A further emphasis of the journal is the publication of a selected number of small workshops, which are at the forefront of their field.
