Cocoletzi Física, Astronomía y Matemáticas low semiconductors dimensional structures Groundstate energy of screened excitons We used a simple variational approach to account for the difference in the electron and hole effective masses in Wannier-Mott excitons intype-II semiconducting heterostructures in which the electron is constrained in an one-dimensional quantum wire (1DQW) and the hole is ina two-dimensional quantum layer (2DQL) perpendicular to the wire or viceversa. The resulting Schrödinger equation is similar to that of a3D bulk exciton because the number of free (nonconfined) variables is three; two coming from the 2DQL and one from the 1DQW. In thissystem the effective electron-hole interaction depends on the confinement potentials. 2005 artículo científico 0035-001X https://www.redalyc.org/articulo.oa?id=57064007 https://www.redalyc.org/journal/570/57064007/ https://www.redalyc.org/journal/570/57064007/html/ https://www.redalyc.org/journal/570/57064007/57064007.epub https://www.redalyc.org/journal/570/57064007/movil en http://www.redalyc.org/revista.oa?id=570 Revista Mexicana de Física application/pdf Sociedad Mexicana de Física A.C.
