ONELL, María  y  LAZO, Edmundo. GENERACIÓN DE ESTADOS EXTENDIDOS EN MODELOS DESORDENADOS CON IMPUREZAS TIPO DELTA. Rev. Fac. Ing. - Univ. Tarapacá [online]. 2002, vol.10, pp.63-66. ISSN 0718-1337.  http://dx.doi.org/10.4067/S0718-13372002001000008.

In this work we study a 1D system with delta type impurities with random amplitudes. This system is diluted introducing, in alternating way, delta type impurities with constant amplitudes. Using the decimation technique, we demonstrate the existence of two infinite sets of delocalized states. The understanding of the mechanism, which allows the metal-insulator transition, opens the possibility of building electronic devices where that transition is relevant.

Palabras clave : Disorder; deslocalization; Anderson.
