 | This is the sandbox page where you will draft your initial Wikipedia contribution.
If you're starting a new article, you can develop it here until it's ready to go live. If you're working on improvements to an existing article, copy only one section at a time of the article to this sandbox to work on, and be sure to use an edit summary linking to the article you copied from. Do not copy over the entire article. You can find additional instructions here. Remember to save your work regularly using the "Publish page" button. (It just means 'save'; it will still be in the sandbox.) You can add bold formatting to your additions to differentiate them from existing content. |

[edit]The Fermi surface is the sphere of constant radius at the Fermi energy plotted across the range of k wavevectors known as the First Brillouin zone. [1][2] The theory of the Fermi surface is developed from the Free electron model which calculates the filled and unfilled energy of states in a periodic, crystalline lattice. This is done by assuming the electron moves freely through the lattice and by using the kinetic energy of the moving electron and the potential the electron experiences from the atoms of the lattice to determine the wavefunction of the electron and calculate the electronic energy bands.[1] The Fermi surface can be used to predict electronic properties as it defines the filled and unfilled bands in three dimensional materials.[2]
