  The internal structure of a composite fermion is investigated for a two
dimensional parabolic quantum dot containing three electrons. A Yukawa screened
Coulomb interaction is assumed, which allows us to discuss the evolution of the
electron-vortex correlations from the Coulomb interaction limit to the contact
potential limit. The vortex structure approaches the Laughlin limit
non-monotonically through the formation of intermediate composite fermions in
which a flip of the spatial orientation of the vortices with respect to the
position of the electrons is observed. Only when we limit ourselves to the
lowest Landau level (LLL) approximation the flip appears through the formation
of an intermediate giant vortex at specific values of the screening length.
Beyond the LLL approximation antivortices appear in the internal structure of
the intermediate composite fermions which prevent the nucleation of giant
vortices. We also studied the system of five electrons and show that the
mechanism of the flip of the vortex orientation found for three-electron system
is reproduced for higher number of electrons.
