Abstract
We have studied the self-capacitance dependence of zero-bias resistanc e in two-dimensional arrays of highly resistive small tunnel junctions . Deviation from the square-root-cusp behavior is more prominent in ar rays with smaller screening length. The results suggest that the finit eness of the screening length is responsible for disappearance of the charge Kosterlitz-Thouless (KT) transition in these arrays.
