Mikhailov Física, Astronomía y Matemáticas Self Binding energies assembled quantum dot Adiabatic approximation The ground state energies of off-axis negatively charged donors in axially symmetrical quantum dots, withdifferent shapes but in all cases with a small height-to-base radius aspect ratio are calculated in adiabatic approximationby using the Hylleraas-type trial function. The dependencies of the neutral and negative donorbinding energies and their ratios on the base radius in the pyramid, lens and disk are calculated and comparedwith previously obtained results for the spherical quantum dot. We also present the contour plots of the bindingenergies of the neutral and negative donors with different positions along a vertical cross section in the middleof the quantum dots. 2006 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46436521 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 |
