To study the interactions between electrons in a material, physicists have come up with a number of tricks over the years.

Researchers have developed a method by which artificial crystal lattices with a large lattice constant can be created in a semiconductor material. The large lattice constant leads to a reduced ...

Remember that the lattice arrangement is giant - for example, a single grain of salt may contain 1.2 × 10 18 (1,200,000,000,000,000,000) ions. The lattice arrangement continues in three dimensions.
