Increasing the number of legs in the ladders provides a step-wise approach toward the two-dimensional copper-oxygen plane, that structure believed to be a key to high temperature superconductivity. Short-range spin correlations in ladders have been predicted to lead to formation of hole pairs favorable for superconductivity, once enough holes are introduced onto the ladders by doping.
