A theoretical description is presented for a single‐electron transport through a vertical gated quantum dot. Using the configuration interaction method we study the correlation effects in the gated quantum dots. We have found that the electron‐electron correlation only slightly changes the single‐electron tunnelling conditions in the absence of an external magnetic field, but has a pronounced influence on the magnetic‐field induced phase transitions in few‐electron systems confined in quantum dots.
