Semiconductor physics
There are 5 states of matter: Solid, liquid, gas, plasma (ionized gas) , and a Bose-Einstein condensate (quantum effects on a macroscopic scale).
Crystal Lattice
Semiconductor physics focuses on the solid state of matter in the form of crystals.
Crystals are formed when atoms are arranged in repeating structures called the crystal lattice. The recurrent structure which forms the crystal lattice is referred to a a cell.
Some popular cell names are
FCC= Face Centered Cubic
BCC = Body Centered Cubic
There are 14 different Bravais lattice configurations
| Crystal System | Lattice type |
| Cubic | Simple, Face Centered, Body Centered |
| Tetragonal | Simple, Body Centered |
| Orthorhombic | Simple, Face Centered, Body Centered, End Centered |
| Monoclinic | Simple, End Centered |
| Rhombohedral | Simple |
| Triclinic | Simple |
| Hexagonal | Simple |
