SBH: Schottky barrier height  
 
Schottky barrier height (SBH).  
 
The SBH is the rectifying barrier for electrical conduction across the MS (Metal-Semiconductor) junction.
 
The magnitude of the SBH reflects the mismatch in the energy position of the majority carrier band edge of the semiconductor and the metal Fermi level across the MS interface.  
 
At a metal/n-type semiconductor interface, the SBH is the difference between the conduction band minimum and the Fermi level.  
And for a p-type interface, the SBH is the difference between the valence band maximum of the semiconductor and the metal Fermi level.
