1s-like, 2p−-like and 2p+-like States of a Hydrogenoid Impurity in a Cylindrical Quantum Dot Under the Action of an Applied Magnetic Field
The quantum states of a cylindrical quantum dot (CDQ) of GaAs/Ga0.6Al0.4As are studied theoretically with a hydrogen-like impurity inside and under the action of a uniform magnetic field, applied in the axial direction of the cylinder. Using the variational method, the energies and wave functions of...

Usando el método variacional se encontraron las energías y las funciones de onda de los estados de impureza, 1s-like, 2p−-like y 2p+-like, cuando ella se mueve dentro del CQD. Se encontró que existe degeneramiento en la energía de la impureza para los estados 2p−-like y 2p+-like en ausencia de campo magnético. Este degeneramiento se rompe solo al aplicar un campo magnético, indicando un efecto Zeeman en el sistema, asì la variación de la intensidad del campo magnético permite sintonizar la condición resonancia de dos fotones.application/pdfspaspaUniversidad Pedagógica y Tecnológica de Colombiahttps://revistas.uptc.edu.co/index.php/ciencia_en_desarrollo/article/view/14354/13675Ciencia En Desarrollo; Vol. 14 No. 2 (2023): Vol 14, Núm.2 (2023): Julio-Diciembre; 69-73Ciencia en Desarrollo; Vol. 14 Núm. 2 (2023): Vol 14, Núm.2 (2023): Julio-Diciembre; 69-732462-76580121-7488Punto cuántico cilíndrico, impureza hidrogenoide, campo magnético.Cylindrical quantum dot, hydrogenoid impurity, magnetic field.1s-like, 2p−-like and 2p+-like States of a Hydrogenoid Impurity in a Cylindrical Quantum Dot Under the Action of an Applied Magnetic FieldEstados 1s-like, 2p−-like y 2p+-like de una impureza hidrogenoide en un punto cuántico cilíndrico bajo la acción de un campo magnético aplicadoinfo:eu-repo/semantics/articlehttp://purl.org/coar/version/c_970fb48d4fbd8a85http://purl.org/coar/resource_type/c_2df8fbb1http://purl.org/coar/access_right/c_abf2Portacio, A.
