摘要

Correlation energy in 1s ? 1s and 1s ? 2s states of a two-electron spherical quantum dot with finite confining potential is calculated using the effective mass approximation, variational method and mean value theorem. The results show that the correlation energy is more significant for dots of smaller radii and larger barrier heights. The correlation energy decreases as the radius increases. The results are compared to other investigations.
