Effect of the aluminum concentration on the second harmonic generation in a quantum dot of AsGa/AsGa1−xAlx
The effect of aluminum concentration on the second harmonic generation (SHG) in a cylindrical quantum dot (CQD) is studied theoretically, using the density matrix formalism and a perturbative procedure. The energy levels and wave functions of an electron in the CQD were obtained by solving the time-...

Los niveles de energía y las funciones de onda de un electrón en el CQD se obtuvieron solucionando la ecuación de Schrödinger independiente del tiempo en el marco de la aproximación de masa efectiva. Los cálculos numéricos se efectúan para un CQD de AsGa/AsGa1−xAlx. Se encontró que el aumento de la concentración de alumnio produce una disminución de la intensidad de la SHG y un corrimiento al azul en los picos resonantes de la respuesta óptica objeto de estudio.application/pdfspaspaUniversidad Pedagógica y Tecnológica de Colombiahttps://revistas.uptc.edu.co/index.php/ciencia_en_desarrollo/article/view/13324/12521Ciencia En Desarrollo; Vol. 13 No. 1 (2022): Vol. 13 Núm. 1 (2022): Vol 13, Núm.1 (2022): Enero-Junio; 57-64Ciencia en Desarrollo; Vol. 13 Núm. 1 (2022): Vol. 13 Núm. 1 (2022): Vol 13, Núm.1 (2022): Enero-Junio; 57-642462-76580121-7488Punto cuántico cilíndrico, generación de segundo armónico.Cylindrical quantum dot, Second harmonic generation.Effect of the aluminum concentration on the second harmonic generation in a quantum dot of AsGa/AsGa1−xAlxEfecto de la concentración de Aluminio sobre la generación del segundo armónico en un punto cuántico de AsGa/AsGa1−xAlxinfo:eu-repo/semantics/articlehttp://purl.org/coar/version/c_970fb48d4fbd8a85http://purl.org/coar/resource_type/c_2df8fbb1http://purl.org/coar/access_right/c_abf2Montes Macea, Alexander JoseCano, L.E.Portacio , Alfonso001/15328oai:repositorio.uptc.edu.co:001/153282025-07-18 10:56:46.287metadata.onlyhttps://repositorio.uptc.edu.coRepositorio Institucional UPTCrepositorio.uptc@uptc.edu.co |
