Unit Cells: The Simplest Repeating Unit in a Crystal
The structure of solids can be described as if they were
three-dimensional analogs of a piece of wallpaper. Wallpaper has a
regular repeating design that extends from one edge to the other.
Crystals have a similar repeating design, but in this case the
design extends in three dimensions from one edge of the solid to
the other. We can unambiguously describe a piece of wallpaper by...
