+ | The **work function** is the minimum thermodynamic work needed to remove an electron from a solid (or surface) to a point in the vacuum. The work function is not a characteristic of a bulk material, but rather a property of the surface of the material. | ||
+ | The work function //W// for a given surface is defined by the difference between Fermi level and electrostatic potential in the vacuum: | ||
+ | |||
+ | $W = -e\phi - E_f$ | ||
+ | |||
+ | where $\phi$ is the electrostatic potential in the vacuum and $E_f$ is the Fermi level of the surface. | ||
