Metal work functions
WebThe factors which determine the work function of a metal are described in a qualitative way. The work function is defined as the difference in energy between a lattice with an … Webdiagram of the metal and the semiconductor, and align them using the same vacuum level as depicted in Figure 2. Figure 2A shows the work function of the metal with respect to the Fermi level. Figure 2B shows the work function of a p-type semiconductor, including the conduction band valence band, Fermi level and electron affinity ( S
