This article analyzes the behavior of electric charge carriers (electrons and holes) in a semiconductor material with metal contacts under the thermodynamic equilibrium condition. Expressions were obtained for the concentrations of the electrons and holes, as well as for the Debye Radius (r D ) both in the general bipolar case, and in the particular cases of n,p and intrinsic type materials. Based on the previous expressions, the case is analyzed when the quasi-neutrality phenomenon appears in a semiconductor material.

Keywords : Charge doolie; metal-semiconductor contact; quasi neutrality.
