# Exercise 3.2-2 Interface Polarization

| Look at a grain boundary in a simple ionic crystal. Take two grains, for example, that are only rotated with respect to each other and are joined along some grain boundary as shown below
|  | Construct a grain boundary by filling in material
|  |  | Show that in most cases the boundary will be charged and contain dipoles
| Link to the solution
