Fermi energy (density of electron)

Click For Summary
SUMMARY

The discussion focuses on calculating Fermi energy by determining the electron density of materials, specifically using aluminum as an example. To find the electron density, one must first ascertain the density of atoms in the material. In the case of aluminum, the density of atoms must be doubled to accurately reflect the density of conduction electrons, as aluminum has a valence of two, indicating two conduction electrons per atom. Understanding when and how to adjust this density is crucial for accurate calculations.

PREREQUISITES
  • Understanding of Fermi energy concepts

To find the Fermi energy I need to find the electron density of the material and that I can do by finding the density of atoms in the material in some instances this same density.
From what I gather it's not always that way Sometimes you have to multiply a certain number
For example, aluminum should double in 3 the density of atoms to know the density of electrons.
I want to know how I know when I need to double? How much I need to double?
Thank you

Isn't it because the valence of Aluminum is two? It's the number of conduction electrons per atom.
