WebOverview Fingerprint Abstract Gold clusters with the sizes close to the Fermi wavelength of electron shows interesting quantum size effects. Linear and nonlinear optical properties show dramatic trends when the sizes of clusters are in the range of quantum confinement. Webwhere k F is the Fermi wave number, n s is the sheet carrier concentration, m* is the effective mass, and E F is the Fermi energy. At low temperatures, current in devices is passed by carriers having an energy close to the Fermi energy, so that the Fermi wavelength becomes the relevant wavelength.

The Fermi energy is a concept in quantum mechanics usually referring to the energy difference between the highest and lowest occupied single-particle states in a quantum system of non-interacting fermions at absolute zero temperature. In a Fermi gas, the lowest occupied state is taken to have zero kinetic energy, whereas in a metal, the lowest occupied state is typically taken to mean the bottom of the conduction band.
