Electro-optical properties of rectangle-shaped crater quantum rings under orthogonal electric and magnetic fields
The electronic and optical properties of an electron in realistic rectangle-shaped crater quantum rings under orthogonal electric and magnetic fields have been theoretically studied. The Schrödinger wave equation was solved using the finite element method within the effective mass approximation. A Stark effect with anomalous oscillatory behavior was observed for electric field strengths less than 10 kV/cm. The threading magnetic field leads to the formation of damped oscillations in the absorption coefficient peaks, which are closely related both to the Aharonov-Bohm oscillations and to a shift of the absorption peaks towards blue or red, depending on the dimensions and morphology of the central crater. Our model is sufficiently flexible such that several results appear as particular cases of the quantum ring with a rectangular central crater.
期刊介绍：
Physics Letters A offers an exciting publication outlet for novel and frontier physics. It encourages the submission of new research on: condensed matter physics, theoretical physics, nonlinear science, statistical physics, mathematical and computational physics, general and cross-disciplinary physics (including foundations), atomic, molecular and cluster physics, plasma and fluid physics, optical physics, biological physics and nanoscience. No articles on High Energy and Nuclear Physics are published in Physics Letters A. The journal''s high standard and wide dissemination ensures a broad readership amongst the physics community. Rapid publication times and flexible length restrictions give Physics Letters A the edge over other journals in the field.
