19. A particular protocol was developed, including double rinsing in pure acetone in ultrasound bath, rinsing in the alcohol, and finally drying under pure dry nitrogen.

22. The YBCO data are normalized with respect to the parabolic part of the spectral background, as the inset in fig. 2 shows. This procedure does not affect the DOS at zero bias.
23. In retrospect one does find dip-hump spectral features in previous works. Unfortunately, poor tunneling conditions made their analysis uncertain.
