Question

Calculate the interatomic spacing in A of the germanium plane having the Miller indices of (111 ). The lattice parameter of Ge is 0.565 nm.

Answer 1

0.3262 nm

Step-by-step 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
`d=(a)/(√(h^2+k^2+l^2))=(0.565)/(√(1^2+1^2+!^2))=(0.565)/(√(3))=0.3262nm`

So the inter atomic spacing in the germanium plane will be 0.3262 nm
