【摘要】 本文采用 DSC、XRD、TEM 和瞬态反射率 R—温度 T,分析了 Sb₂Se₃,SbSe 和 Sb₃Se₂薄膜的非品析晶过程,研究了超化学计量 Sb₂Se₃的 Sb 对晶化行为的影响,发现晶体形貌和析品速率随着超量 Sb 的增加而变化。在薄膜中,Sb 起着晶核作用,加快析晶速率。更多还原

【Abstract】 In this paper,DSC.XRD.TEM.and Transient R-T were used to investigatethe amorphous crystalline transformation of Sb₂Se₃,SbSe and Sb₃Se₂ films,and tostudy the effects of extra quantity Sb of stoichiometry Sb₂Se₃ on their crystalliza-tion behavior.It was found that the morphology of crystallite and the rate of cry-stallization were changed with the increasing amount of the extra quantity of Sb.In films Sb could act as the nucleation center and speed up the rate of crystalliza-tion.更多还原
