How the potential barrier from metal to semiconductor for electrons in the metal-semiconductor junction (Schottky junction) is calculated? In other words why that potential barrier is q([itex]\phi_m -X_s[/itex])?
[itex]\phi_m[/itex] is metal work function and [itex]X_s[/itex] is electron affinity of semiconductor.
