GIL-CORRALES, John Alexander; MORALES-ARAMBURO, Álvaro Luis  and  DUQUE-ECHEVERRI, Carlos Alberto. Electronic States of Pyramidal and Conical Quantum Dots. Rev.EIA.Esc.Ing.Antioq [online]. 2018, vol.15, n.30, pp.161-175. ISSN 1794-1237.  https://doi.org/10.24050/reia.v15i30.1257.

The electronic states confined in a quantum dot, of GaAs, of pyramidal and conical shape have been investigated through the quasi-analytical approach, valid for small angles, and the finite element method to include all angles and heights. The results of the confinement energy have been reported according to the shape and size of both structures and finally the approximate values have been compared with the exact values obtained from the finite element method.

Keywords : Pyramidal quantum dot; Conical quantum dot; Quasi-analytical aproximation; GaAs; Finite elements.
