Abstract
We have done a series of tricrystal experiments to investigate the doping dependence of pairing symmetry in various hole-doped cuprate superconductors with doping levels ranging from underdoped to overdoped regimes. The results of this work have indicated that the dx2−y2dx2−y2 pair state is robust against a wide range of doping variation. Our findings underscore the importance of strong on-site Coulomb repulsion in pairing interaction, which favors the dx2−y2dx2−y2-wave pairing symmetry over pair states with other symmetries.
