Answer:
0.3262 nm
Explanation:
We have given the miller indices coordinates (h,k,l ) =(111)
Lattice parameter of the Ge is a=0.565 nm
As we know that inter atomic spacing [tex]d=\frac{a}{\sqrt{h^2+k^2+l^2}}=\frac{0.565}{\sqrt{1^2+1^2+!^2}}=\frac{0.565}{\sqrt{3}}=0.3262nm[/tex]
So the inter atomic spacing in the germanium plane will be 0.3262 nm
