Semiconductor Fundamentals

\(\Phi_M\) - metal workfunction. Minimum energy needed to release an electron from a metal.

\(E_p = h\nu = \frac{hc}{\lambda}\) - energy of a photon.

\(E_k = \frac{p^2}{2m}\) - kinetic energy as a function of momentum and mass.

\(p=\frac{h}{\lambda}\) - momentum of a photon.

\(E_k = E_p - \Phi_m\) - kinetic energy of an electron released from a metal by a photon with energy \(E_p\).
