Se obtuvieron expresiones para las concentraciones de los electrones y huecos, así como para el Radio de Debye (r  D ) tanto en el caso general bipolar, como para los casos particulares de materiales tipo n,p e intrínseco. Con base a las expresiones anteriores se analiza el caso cuando aparece el fenómeno de cuasineutralidad en un material semiconductor.]]></p></abstract>

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.
