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。

A novel layout of IC transformer is proposed to achieve both high turn ratio and coupling coefficient in this paper. In order to discuss the coupling coefficient, the layouts are designed with different turn ratio. The thesis is mainly includes of three experiment topics. The multi-stack structure is proposed to achieve prior goal in first topic. Two groups of proposed devices are designed to maintain identical self- inductances in transformer's primary and secondary coils. Total six devices are fabricated in foundry 90-nm CMOS technology. Using the 9 and 5 metal layers in primary and secondary coils in a specific layout, measurement results show that the transformer has the largest benefit using the bottommost return layer in layout design. In one word, the adoption of more metal layers to construct different turn ratio transformer shows not only improving the N value but also saving the chip area in this experiment.
中文摘要本文是针对不同圈数比变压器探讨其耦合量的变化,并且期望其变压器能同时达到高圈数比及高耦合系数的特性,本论文主要可分为三个实验主题,首先第一个主题提出以90nm CMOS制程技术实现的多层金属层的布局方式,并以相同的一、二次侧自感值分为两组,利用不同返回层来达到不同的圈数比,且从量测结果可以得知,在变压器布局设计上使用最底金属层来作返回层会得到较好的特性,最后从此实验得知一结论,利用合适的多层金属架构达到不同的圈数比,不仅可以改善圈数比,还可以缩小晶片面积。

Thermal oxidation treatment can increase the surface hardness and elastic modulus significantly and reduce the E /H ratio of the TC4, which indicate the treatment can enhance the wear resistance of TC4 alloy. Long time treatment can increase the thickness of the oxide layer, but the outside layer is apt to desquamate during the scratching. The oxide layer closing to substrate has better bonding properties, but microcrack forms as a result of high stress loading, which lead the layer to flake off completely.
长时间的高温氧化可以增加氧化层的厚度,但在划擦过程中氧化层发生两次脱落,表明氧化层由外表层和次外层组成,外层结合力差,易发生一次脆性剥落,内层与基体的结合强度较高,但在较大载荷作用下会产生微裂纹,导致氧化层的二次剥落。
