The effect of doping glassy Se₉₈Te₂ alloy with Cd and Zn impurities on the thermally crystallization behavior is investigated using differential thermal analysis (DTA) at different heating rates. In this study, the glass transition activation energy (E_g), the crystallization activation energy (E_c), Avrami exponent (n), and the frequency factor (k_o) are calculated to understand the mechanism of crystal growth using various theoretical models. All these models depend on the characteristic temperatures obtained from the DTA curves of the investigated samples. The obtained values of n indicate that nucleation process occurs at two-dimensional growth for both Se₉₈Te₂ and Se₉₆Te₂Zn₂ while for Se₉₆Te₂Cd₂ the nucleation process occurs at three-dimensional growth. Differential thermal stability parameters are calculated for the studied system and found to decrease in the sequence (SeTe) > (SeTeZn) > (SeTeCd). The effect of Cd and Zn on different kinetic parameters of the investigated glassy Se₉₈Te₂ alloy is also studied.

采用差热分析（​​DTA）研究了在不同加热速率下，Cd和Zn杂质掺杂玻璃态Se ₉₈ Te ₂合金对热结晶行为的影响。在这项研究中，玻璃化转变活化能（E _g），结晶活化能（E _c），Avrami指数（n）和频率因子（k _o可以使用各种理论模型来计算），以了解晶体生长的机制。所有这些模型都取决于从研究样品的DTA曲线获得的特征温度。获得的n值表明，Se ₉₈ Te ₂和Se ₉₆ Te ₂ Zn ₂都在二维生长时发生成核过程，而Se ₉₆ Te ₂ Cd _2则成核过程成核过程发生在三维生长。计算出所研究系统的热稳定性差参数，发现其降低顺序为（SeTe）>（SeTeZn）>（SeTeCd）。还研究了Cd和Zn对所研究的玻璃态Se ₉₈ Te ₂合金不同动力学参数的影响。
