Tables

Generic image for table
Table I.

Matrix of pair of monoelectronic states to form the elements of the density matrix of the system. In this example we considered and the matrix shown the new labels of the elements of the density matrix and the corresponding pair of monoelectronic states. We followed the case here depicted. The states and the pairs have defined parity and we form a symmetric subspace and an antisymmetric subspace.

Table II.

Electronic states of the delta-doped QW for different areal concentration of charge carriers or impurity atoms. There are no results of states for the cases of ; without XC interaction.

Generic image for table
Table III.

Parameters of the delta-doped QW we will use for the calculations.

Generic image for table
Table IV.

Pairs of coordinates of the local extrema of the wave functions for the first five states, as a function of the areal density. One half of the wave function is described. The table is divided into two portions. The cases of ; have no wave functions when we have no XC included.
