| contents | Tight-binding hamiltonians for the study of the electronic structure of the valence band of the II-VI binary/ternary-alloy interfaces R. Baquero D. Olguín Física, Astronomía y Matemáticas II VI alloys binding method electronic band structure: tight We present an electronic band structure calculation of the valence band of the II-VI binary/ternaryalloy interfaces. Weuse the empirical tight-binding method and the surface Greens function matching method. For the ternary alloys we useour previously set Hamiltonians. They describe well the band gap change with composition obtained experimentally. Withthis data, we go on to describe the interface states. At the interface domain, we find three non-dispersive- and twointerface-states besides the known bulk bands. We make use of the available theoretical calculations for the (001)-orientedsurfaces of the binary compounds and for the binary/binary interfaces to compare our new results with 2000 artículo científico 1665-3521 https://www.redalyc.org/articulo.oa?id=94201007 en http://www.redalyc.org/revista.oa?id=942 Superficies y vacío application/pdf Sociedad Mexicana de Ciencia y Tecnología de Superficies y Materiales A.C.
