Abstract
The competition between strong electronic correlations and charge orde ring due to an external potential are studied in the infinite-U Hubbar d model by means of the slave-boson technique. The quasi-particle scre ening of the external potential produces a reduction of the charge-den sity-wave amplitude with respect to the non-interacting (i.e. U = 0) c ase. The mechanism becomes more and more effective as the number of el ectrons per site is increased towards unity.
