摘要：
We report the controlled and systematic modification with scanning tunneling microscope (STM) of the surface in bilayer YBa2Cu3Oy/PrBa2Cu3Oy (120/960) films. The number in parenthesis refers to the thickness of each layer in units of Angstrom. The bias voltage of the tip was kept negative and was varied from - 600 to - 1200 mV. The tip was operated in a constant tunneling mode with 0.3 - 0.6 nA of tunneling current and the scanning rate was 1 Hz. Etching of the YBCO/PBCO (120/960) begins with a nucleation of holes and can be achieved by successive scanning a fixed area.
