1/28/20235晶体的一个基本特点是具有方向性，沿晶格的不同方向晶体性质不同。布拉伐格子的格点可以看成分裂在一系列相互平行的直线系上，这些直线系称为晶列。同一个格子可以形成方向不同的晶列，每一个晶列定义了一个反向，称为晶向。crystal orientation1/28/20236 以晶胞基矢定义的互质整数，用以表示晶面的方向。确定某平面在直角坐标系 3个轴上的截点，并以晶格常数为单位测得相应的截距。取截距的倒数，然后约简为 3 个没有公约数的整数，即将其化简成最简单的整数比。将此结果以“（hkl）”表示，即为此平面的密勒指数。Miller indexTerminology silicon wafer 硅晶圆Ion implantation 离子注入wafer Fabrication 晶圆制造radio frequency amplifiers
