The calculation of deep levels associated with NN pair impurities in GaP


Author(s): Zhang Yue

Abstract: On the basis of the approach of Green’s function, the present work establishes a calculation theory for the deep levels associated with NN pair impurities in GaP by use of a set of special points in the Brillouin zone. Moreover, the paper employs four radial functions rather than the plane wave functions as the Lowdin orbitals for 2s2p electrons to construct the symmetrical functions of the GaP: NN system. Applying this theory to A1 state which is more required to be considered in the applications, the paper obtains a detail scheme of calculating the 16 matrices Eij(i=1, 2, 3, 4; j=1, 2, 3, 4) and therefore the deep levels associated with the closest – neighbour nitrogen pairs in GaP, which can directly calculate out the numerical results of the energy levels if we know the experimental parameters J0 and J1.
