description |
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 the impurity states, 1s-like, 2p−-like and 2p+-like, when she moves inside the CQD. It was found that there is degeneracy in the impurity energy for the 2p−-like and 2p+-like states in the absence of a magnetic field. This degeneracy is broken only by applying a magnetic field, indicating a Zeeman effect in the system, thus, the variation of the intensity of the magnetic field allows to tune the resonance condition of two photons.

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 the impurity states, 1s-like, 2p−-like and 2p+-like, when she moves inside the CQD. It was found that there is degeneracy in the impurity energy for the 2p−-like and 2p+-like states in the absence of a magnetic field.

Se estudia teóricamente los estados cuánticos de un punto cuántico cilíndrico, (CDQ) de GaAs/Ga0,6Al0,4As con una impureza hidrogenoide en su interior y bajo la acción de un campo magnético uniforme, aplicado en la dirección axial del cilindro. 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.
