Depth of potential well for free electrons in a metal

Reference no: EM13655839

The depth of the potential well for free electrons in a metal can be accurately determined by observing that the photoelectricwork function is the energy necessary to remove an electron at thetop of the occupied states from the metal; an electron in such astate has the fermi energy assuming each atom provides one freeelectron to the gas compute the depth of the well for the freeelectrons in gold. the work function for gold is 4.8 eV.
