Edge widths definition

Figure 3.16 Shows the definitions of the electron affinity Xs of the semiconductor and the work functions of the semiconductor, Og and metal, Figure 3.16 Shows the definitions of the electron affinity Xs of the semiconductor and the work functions of the semiconductor, Og and metal, <D . Also indicated are the depletion width, W, the Fermi levels, band edges, and the Schottky barrier heights, Ob. Note that Schottky barriers to both n and p-type semiconductors exist but that to calculate the barrier for the p-type semiconductor you need to compare the valence band edge with the metal work function while for the n-type material it is the conduction band that is compared to the work function.
