A new real-space correlated-basis-functions approach for electron correlations of the semiconductor inversion layer

Wei-guo Feng, Hongwei Wang, Xiang Ying Wu

Based on the real-space correlated-basis-functions theory and the collective oscillation behaviour of the electron gas with effective Coulomb interaction, the many-body wavefunction is obtained for the quasi-two-dimensional electron system in the semiconductor inversion layer. The pair-correlation function and the correlation energy of the system have been calculated by the integro-differential method. A comparison with other previous theoretical results is also made. The new theoretical approach and its numerical results show that the pair-correlation functions are definitely positive and satisfy the normalisation condition.

Based on the Correlated-Basis-Functions (CBF) theory, we have obtained the many-body wave function for the quasi-two-dimensional electron system in Al x Ga 1-x As-GaAs heterojunction. The pair-correlation functions g(R) were calculated, and a new method for the calculation of correlation energy was also presented.

MAO HUI-MING, Shao Jin-Shan, Wang Hongwei +3 more

For the quasi one-dimensional electron systems with coulomb interaction, a new model is presented. The form of effective Coulomb potential is derived. Based on the correlated wave function theory, the many-body wave function is obtained on the basis of the collective oscillation behavior of the electron gas. The pair correlation functions and correlation energies of the different electron densities are obtained. The pair correlation functions obtained in this paper are positive definite and satisfy the normalization condition.
