Far-infrared spectroscopy of nanoscopic InAs rings Emperador, Agustí Pi Pericay, Martí Barranco Gómez, Manuel Lorke, Axel Nanoestructures Semiconductors Espectre infraroig Nanostructures Semiconductors Vibrational spectra We have employed time-dependent local-spin-density theory to analyze the far-infrared transmission spectrum of InAs self-assembled nanoscopic rings recently reported [A. Lorke et al., Phys. Rev. Lett. (to be published)]. The overall agreement between theory and experiment is fairly good, which on the one hand confirms that the experimental peaks indeed reflect the ringlike structure of the sample, and on the other hand, asseses the suitability of the theoretical method to describe such nanostructures. The addition energies of one- and two-electron rings are also reported and compared with the corresponding capacitance spectra 2009-12-24T10:32:02Z 2009-12-24T10:32:02Z 2000 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Reproducció digital del document publicat en format paper, proporcionada per PROLA i http://dx.doi.org/10.1103/PhysRevB.62.4573 Physical Review B, 2000, vol. 62, núm. 7, p. 4573-4577 http://dx.doi.org/10.1103/PhysRevB.62.4573 (c) The American Physical Society, 2000 info:eu-repo/semantics/openAccess The American Physical Society Articles publicats en revistes (Física Quàntica i Astrofísica)
