We have performed point-contact tunneling measurements on overdoped Bi2Sr1.
94La0.06CuO(6+6) (Bi2201) single crystals with gold tips. Sharp zero bias c
onductance peak (ZBCP) was observed. The data were analyzed with extended B
TK theory. We found that the dx(2)-y(2)-wave symmetry gap parameter can fit
the data nicely.
