| 摘 要： | 通过实验对比,研究了CH3CSNH2钝化对铁磁金属与GaAs界面处As扩散行为的影响.发现S钝化处理改变了表面As元素的化学环境,减弱了As元素向铁磁金属外延层中的扩散现象,削弱了As与铁磁金属的反应,形成了较窄的反应层,并且改善了界面磁性.初步探讨了S钝化影响As扩散的原因.关键词：S钝化半导体界面电子结构磁性

| Abstract: | The influence of CH3CSNH2 passivation on diffusion at interface between ferromagnetic metals and GaAs has been studied. The experimental results show that sulfur passivation can change the chemical environment of As element , prevent As from diffusing into ferromagnetic metal overlayer, weaken the reaction of As with ferromagnetic metals and enhance the magnetism of the interface. Furthermore, we discussed the reason that S passivation can prevent As atoms diffusion. |
