BiFeO3/PZT multilayer capacitor was prepared on Pt(100) /Ti/SiO2/Si(100) substrate.PZT buffer layer was derived by MOCVD method(label:PZT1) and sputtering method(label:PZT2) respectively.XRD analysis
The availability of resources for economic activities differs between regions,and the importance of the resources is consequently observed to be different within regions compared to a global scale.Wit
本研究中,采用以下主要步骤:先在p-型Si的绒面上,进行磷扩散形成同质p-n结,再低温热氧化生长超薄SiO2层,然后利用射频磁控溅射沉积ITO减反射/收集电极膜,成功制备了一种新型ITO/SiO2/np晶硅SINP结构蓝紫光电池.通过X-光衍射(XRD)、扫描电镜(SEM)、紫外-可见光透射谱(UV-VIS),以及霍尔效应(Halleffect)测量方法,表征了高质量ITO薄膜的微结构、光学与电学
运用数值方法,系统研究了肖特基接触单层有机太阳能电池的阴极功函数、载流子迁移率和温度对短路电流的影响,得到了短路电流随阴极功函数、载流子迁移率和温度变化的定量关系,这为以后的有机太阳能电池实验研究提供理论基础.
After revisiting models for the ferroelectric relaxors,we notice that the models can be classified into two categories.One group models are directly based upon the compositional fluctuations,such as S
