Lanthanum-modified lead zirconate titanate (PLZT) thin films, with the La/Zr/Ti ratio being 9/63/37, were deposited on indium tin oxide (ITO)-coated glass substrate by R.F. magnetron sputtering method. Effects of heat-treatment conditions on the structure and chemical homogeneity of the PLZT thin films were investigated by X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS). The PLZT thin films with desired perovskite structure were obtained after covered with lead oxide and then annealed at 625℃ for 150 min. The binding energy of Pb4f7/2, Ti2p3/2, Zr3d5/2, La3d5/2, and O1s in PLZT thin films were: 138.3, 455.7, 181.2, 835.9, and 529.4 eV, respectively. The excess lead oxide in the PLZT thin films promoted the perovskite structure formation, and baffled the movement of TiO2 and ZrO2 as well. A small quatity of TiO2 and ZrO2 coexisted with PLZT in the surface of samples. And the lack of oxygen inside the films resulted in the valence decrease of a little part of Ti's from +4 to +2.

在室温条件下，利用自行设计的平面“S”形磁过滤等离子体设备，在（111）面单晶硅上制备TiN薄膜，通过改变基底偏压和反应气体成分，即通过改变氮气和氩气的气体流量来改变沉积离子的能量和密度，从离子轰击的角度研究了沉积条件对TiN薄膜织构的影响。对薄膜的表面形貌进行观察，（θ～2θ）和1.5°掠入射2种X射线衍射方法对薄膜晶体结构和晶面取向进行了分析，对薄膜进行了电子衍射研究。结果显示磁过滤等离子制备的TiN薄膜表面平整光滑，颗粒尺寸为20～70nm，且基底偏压和氩气流量的增大促使薄膜发生（111）面的择优取向，且（111）晶面与膜表面平行，而在高氩气流量的情况下，（200）和（220）面在薄膜平面也发生了定向排列。

Single crystals of ZnB2O4 have been grown from a supercooled molten ZnO-B2O3 system on multiwall carbon nanotubes. Transmission electron microscopy investigations indicated that the originally curly carbon nanotubes were well straightened after the single-crystal coating. The coating and straightening mechanism are discussed.

采用柱状靶多弧直流磁控溅射法，100℃基底温度下在玻璃衬底上制备了纳米氮化铜（Cu3N）薄膜。用X射线衍射研究了不同氮气分压对Cu3N薄膜晶体结构及晶粒尺寸的影响。结果显示薄膜由Cu3N和Cu的纳米微晶复合而成，其中Cu3N纳米微晶具有立方反ReO3结构。通过原子力显微镜对薄膜表征显示，膜表面比较光滑，具有较低的粗糙度。X射线光电子能谱对薄膜表面的成分分析表明，Cu3N薄膜表面铜元素同时以+1价和+2价存在。Cu3N的Cu2p3P2，Cu2p1P2及N1s峰分别位于93217，95217和39919eV，Cu2p原子自旋2轨道耦合裂分能量间距为20eV。用台阶仪和四探针方法测量了薄膜的厚度及电阻率，薄膜的沉积速率和电阻率在很大程度上受到氮气分压的调制。

采用自行研制的实验装置，用阳极弧放电等离子体方法制备了高纯镍纳米粉末。利用X射线衍射（XRD）、透射电子显微镜（TEM）和相应选区电子衍射（ED）、BET吸附等对样品的成分、形貌、晶体结构、晶格常数、粒度及其分布、比表面积进行了分析。建立了关于金属超微粒产生过程的近似模型，分析了纳米粉的形成和生长机制，并对整个工艺过程影响纳米粉性能的各种工艺参数进行了理论探讨。结果表明：所制得的镍纳米粉纯度高，晶格结构与相应的致密体相同，为fcc相结构，平均粒径为47nm，粒径范围在20～70nm，比表面积为14.23m2/g，呈规则的球形链状分布，并发现纳米晶体的晶格常数发生膨胀。
