We investigate a normal metal -- superconductor (point) contact in the limitwhere the number of conducting channels in the metallic wire is reduced to fewchannels. As the effective Fermi energy drops below the gap energy, aconducting band with a width twice the Fermi energy is formed. Depending on themode of operation, the conduction band can be further squeezed, leading tovarious non-linear effects in the current-voltage characteristics such ascurrent saturation, a N-shaped negative differential resistance, bistability,and hysteresis.Comment: 4 pages, RevTeX, three postscript figure
