We present a theoretical study of the unielectronic energy spectra, electron localization, and optical absorption of triangular core-shell quantum rings. We show how these properties depend on geometric details of the triangle, such as side thickness or corners' symmetry. For equilateral triangles, the lowest six energy states (including spin) are grouped(More)
We compare energy levels, carrier localization and optical absorption of a single electron and a pair of interacting carriers confined in a hexagonal quantum ring. We show that many-body levels are multiple degenerate and, contrary to the single-particle case, no repeated energy sequence can be identified. The number of eigenvalues associated with(More)
