Surface pro5le images have been recorded from high-Tc superconducting YBa 2 Cu 4 O 8 using high-resolution transmission electron microscopy. The surface regions are found to be relatively more stable than those of YBa 2 Cu 3 O 7 . The stability of the double CuO chains in the vicinity of a crystal s
