Abstract
The two-dimensional metallic state is studied in a number of Si-MOS structures with peak mobilities varying by a factor of 8.5. The data show a density dependence and disorder dependence of the major features of the scaling function and thus reveal the absence of universal one-parameter scaling over wide density range in the metallic regime.Keywords
