| contents | Excitonic Emission of a Triply Charged Quantum Dot Molecule in a Magnetic Field M. Adames A. S. Camacho Física, Astronomía y Matemáticas Quantum dots Charge excitons Excitons in magnetic fields We calculate the exciton states of a Quantum Dot (QD) and a Quantum Dot Molecule (QDM) in an exact wayfor single, double and triply charged excitons without and with an applied external magnetic field. For the caseof single quantum dot, we reproduce the experimental results reported in [2]. We also calculate the emissionenergies for the neutral molecule QDM as function of the barrier width between the two dots and we find that theCoulomb interaction splits the emission spectra in case of QDM. Concerning hybridization the triply chargedQDM behaves in the same way as the QD, but showing several anticrossings with the lower Landau level of thecontinuum. 2006 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46436510 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.3B Vol.36 |
