Minkowski structure of the Fermion propagator in QED2+1 is evaluated using dispersion like method Including massive fermion loop to the photon spectral function there is no infrared divergences in the gauge d=-1.Screening effects suppress the chiral order parmeter for small numbers of fermion flavour N.We evaluate the order parameter as a function of coupling constant c and N.There exsists a critical region where the chiral symmetry is dynamically broken.
