Confined electron states in two-dimensional HgTe in magnetic field: Quantum-dot versus quantum-ring behavior

We investigate the electron states and optical absorption in square- and hexagonal-shaped two-dimensional (2D) HgTe quantum dots and quantum rings in the presence of a perpendicular magnetic field. The electronic structure is modeled by means of the \(sp^3d^5s^*\) tight-binding method within the nea...
