WebSep 11, 2024 · There are 7 types of unit cells (figure 12.1.a), defined by edge lengths (a,b,c) respectively along the x,y,z axis and angles α, β, and γ. In this class we will only focus on the cubic unit cell, and there are three types of cubic cells that you need to be familiar with, and these are represented in figure 12.1.b. α WebThis is based on particular vectors in the unit cell which span exactly (N) touching atoms (again assuming the atoms are hard spheres). For example, the edge of an SC unit cell spans 2 atoms, thus a=2r. For FCC, 4 atomic radii are spanned across the unit cell face diagonal, so 4r=sqrt(2)*a. BCC has 4 radii spanning across the unit cell 'body ...
