| 摘 要： | 采用脉冲激光沉积(LPA)法,在单晶Si表面制备了调制周期为50nm的不同调制比的TiN/AlN多层膜,并研究了调制比对多层膜微结构和力学性能的影响。扫描电镜(SEM)和原子力显微镜(AFM)显示,薄膜的调制比在1～4之间。并且小调制比下薄膜表面的岛密度小,岛面积过大,分布不均匀,相邻岛之间的起伏较大。X射线衍射(XRD)结果表明,小调制比下,AlN相为明显的(002)择优取向,TiN相主要以(200)、(220)形式存在;调制比增大后,AlN相的择优取向减弱,同时伴随着薄膜晶粒的细化及硬度增强,这一研究结果说明,调制比对多层膜的性质有一定的影响,大调制比会导致Al元素在界面处聚集,并与TiN进行合金化后的形成TiAlN结构,进而对薄膜的硬度产生影响。

| Abstract: | In this study,polycrystalline TiN/AlN multilayer film with various modulation ratios was deposited onto silicon substrate using pulsed laser ablation.The microstructure and the nanoindentation hardness of TiN/AlN multilayer films were also investigated.SEM and AFM confirmed a standard modulation ratio ranging from 1 to 4,the least density and large tracts of island had been found in small modulaton ratio.XRD revealed that an obvious preferred orientation(002) is appeared in AlN phase,and orientation(200)(22... |
