As a result, if the iridescence is produced by thin-film interference, not only the thickness of lamellar structure must be defined within a certain nanometer, but also the refractive index need to be different between lamellar structure. In other words, the chemical composition, refractive index and thickness of exsolution lamellae need form to trinity, such as labradorite, albite, andradite and orthoamphibole. If the iridescent color is produced by grating-diffraction, the lamellar structure just needs to be arrayed regularly, the spacing of the edges of lamellar structure needs to be regular and narrow, but not necessarily within the range of the wavelength of visible light, such as shell of abalone, pearl and opal.
薄膜干涉式晕彩不仅要求宝石内部结构层的厚度必须在一定的纳米范围内,而且结构层内部的折射率也必须有所差别,也即,当结构层由两相组分出溶而成,其化学成分、折射率和结构层厚度形成三位一体时,符合薄膜干涉式晕彩,如拉长石、钠长石、石榴石和角闪石;而光栅式衍射晕彩则仅要求结构层排列规则,边缘狭窄但不需要窄到可见光波长范围内,能使入射光的振幅或位相,或两者同时产生周期性空间调制的结构即可,如鲍贝壳、珍珠和欧泊。

The results showed that the TiN andN films are polycrystalline phase. The properties and structure of TiN films are mainly determined by the N2 mass flow rate, and as the N2 mass flow rate increases, the structure of the TiN films transforms to f.c.c. type leading to better the properties of films. The presence of negative bias voltage can optimize the grain of TiN films, lower the defect proportion and denser the films, which improves the hardness of films. The TiN films conform to the free carrier absorption mechanism and there are many of free electrons with lower N content in TiN films. With the increase of N content, the quantity of free electrons and reflectivity of films decrease, and the plasma frequence shifts to the lower energy, which leads to the regular change of colors of films from silver, yellowy, golden to yellow-red, meanwhile the lightness of films decreases. The goldenN film consists of TiN and ZrN phase, but belongs to a sigle f.c.c. structure with (111) preferred orientation. The Zr-doping dosen't change the position of the valance band, conduction band and forbidden band ofN film, but leads to the presence of new energy levels, which is the reason thatN film remains golden. The transparent hard films with good corrosion resistance and high hardness have been prepared and the further reseachs showed that the grain size of those films is by far smaller than the wave length and the width of forbidden band of those films is very broad, is the reasons that those films are transparent.
研究表明:氮化钛和N 薄膜为多晶态,氮流量决定了氮化钛薄膜的结构和性能,增加氮流量能使氮化钛薄膜的结构向面心立方结构转变,从而得到性能良好的氮化钛薄膜;施加负偏压能优化氮化钛晶粒和减少薄膜中的缺陷,使膜层变得更致密,从而提高薄膜硬度;氮化钛主要遵循自由载流子光吸收,氮含量较少时薄膜中的自由电子数目较多,随着氮含量的增加,薄膜中的自由电子数目不断减少,反射率逐渐降低,等离子体频率向低能端移动,从而使薄膜颜色出现规律变化,由金属色银白色到淡黄、金黄再到红黄,并且薄膜亮度呈下降趋势;金黄色的N 薄膜中存在TiN 和ZrN 的分离相,但其为单一的面心立方结构并具有(111)面择优取向;相对于TiN 薄膜,Zr 掺杂后,并没有使薄膜的导带、价带和禁带发生变化,只是在TiN 禁带内增加了新能级,这也正是掺杂Zr 后,薄膜仍

The result indicated that the AlTiN multilayer coating deposited on high speed steel substrates with alternated nitrogen contents in layers. In each layer, AlTiN exhibited nanocomposites of nanocrystallites embedded into amorphous matrices despite of the nitrogen content. The difference between bilayers was that AlTiN layer with lower nitrogen content had a lower density of nanocrystallites. The AlCN coating deposited on Si (100) substrate appeared a strained layer on substrate in the ilm-substrate interface, which thickness was 3~5 atom layer.

According to the simulated results, it was found that the incident light was not fully absorbed in the solar cell due to a thinner base layer. The un-absorbed incident light could be further reflected by a AuGe/Au mirror layer and absorbed again by the base layer. Thus the disadvantage of the GaAs thin-film cell with a thinner base layer could be solved by the additional reflection from the AuGe/Au mirror with a high reflectivity within 800~1000 nm wavelength. Moreover, the external quantum efficiency in the long wavelength region and short current density were also increased.

The results show that the films are characterized by the amorphous microstructure and mainly composed of Si C bondings, C C bondings as well as a small mount of oxide impurity consorted with Si; the content of the C C bondings decreased after annealing in vacuum, meanwhile the Si C bondings content increased, annealing in vacuum is beneficial to the formation of SiC; after annealing at 800 in air, a thin dense layer of SiO2 formed on the surface, which prevented the oxygen from contacting with the film and effectively protected the inner SiC from oxidizing.

For thinner films, stacking faults are preferred in the scratch process, which increase storage capacity of plastic deformation in the film, and further inhibit the stick slip amplitude in the friction oscillation process. For thicker films, dislocation loops, which glide along slip plane downward to the grain boundary, dominate over the stacking faults, and finally dissipate on the grain boundaries. Since the intergrain stacking faults are inactive in thicker films, the stick slip phenomenon is similar to that in single crystal.
