Finding the lattice constant for a zincblende (modified fcc) crystal ...
Posted on 2006-03-31
I want to know how you would find the lattice constant (edge length) for a crystal unit cell if it is a zincblende, in effect, composed of atoms of two different radii. In this case (a homework problem I'm stuck on) the atoms are In and SB, but generally speaking ... isn't zincblende essentially the same as a diamond structure? How do the differing radii change the standard formulas, ie, the ones I actually know?
