Özet
The Schrodinger description of 2-d finite barrier rectangular quantum dots [1] expanded to Dirac description through transfer matrices and reflection and rotation symmetries of the dot system. Inexactness of wave vector components of spinors is then reduced to two relations which lead to two different bispinors and four quantized transcendental energy relations corresponding to even-even, odd-odd and even-odd, odd-even factorizing functions of each bispinor. In order to show the spin effect on the dot energy levels, the solutions of the transcendental relations of the Schrodinger and Dirac descriptions are plotted. (C) 2014 Elsevier B.V.
