Abstract
Size and shape effects on two-electron spectra and the spin transition in ellipsoidal quantum dots in magnetic fields are studied. Calculated results show that the level crossing of two electrons in quantum dots is dramatically influenced by the shape and size which can strongly change single-electron levels and Coulomb interaction energies. The spin transition is quite different between prolate and oblate quantum dots. The spectra are almost independent of the total spin as the vertical confinement is much weaker than the lateral one. The quantum behaviors of ellipsoidal quantum dots show some relations with those of vertically coupled quantum dots, and they are well explored.
