Flat band potential (E_fb) is an important concept for the system of semiconductor/electrolyte solution. It is a potential when the band is at flat state. It is special characteristics to semiconductors and it can be measured by experiments such as Mott-Schottky curve and the measurement the relationship of photocurrent and applied potentials. Besides, the semiconductor type and its carrier density can be induced from the measurement of E_fb. The band structure including the conductive or valence band position of semiconductor can be obtained from E_fb. This is important for the photocatalysis and photoelectrochemical process of semiconductors, which are related to the applications of solar energy. In this paper, energy band bending of semiconductor and its influence factors are analyzed in detail. It is proposed that the Fermi energy is bended in the interface of semiconductors. Furthermore, the meaning, measurements and applications of E_fb are summarized in order to help the students to understand and use it.
