Oral exam questions on crystal structure
There are questions about Miller indices like:
- Copper has an fcc crystal structure. If you cut it so a (111) plane is exposed, what would the pattern of atoms on the surface look like? How could you determine the pattern of the atoms on the surface experimentally?
- CsCl has an simple cubic crystal structure with two atoms in the basis. If you cut it so a (110) plane is exposed, what would the pattern of atoms on the surface look like? How could you determine the pattern of the atoms on the surface experimentally?
- ...
