Topological structure effect on far-infrared spectra in a GaAs/InAs nanoring

doi:10.1088/1674-1056/21/3/037301

Abstract On the basis of the growth mechanism of a GaAs/InAs nanoring, we propose a fine model which reflects the confinement details of real nanoring. Through calculations of the two-electron energy and far-infrared (FIR) spectra, we find that the ring topological structure and electron-electron interaction have great influence on the FIR spectra. The two unknown transition peaks in the experiment are determined theoretically. The theoretical results are in good agreement with the experiments.

Keywords: nanoring topological structure far-infrared spectrum confinement potential
