| Abstract: | The surface modifications of as-grown superconducting Bi-Sr-Ca-Cu-O (BSCCO) films prepared by radio frequency plasma flash evaporation were carried out with a scanning tunneling microscope (STM). The as-grown films were identified as highly c-axis-oriented, low T_c (80 K) phase Bi_2Sr_2Ca_1Cu_2O_x with some residue such as (Sr,Ca)_3Cu_5O_x from x-ray diffraction patterns. The as-grown film deposited at about 750 °C exhibited a superconducting critical temperature T_c of 76 K and a critical current density J_c of 8.8×10^4 A/cm^2 under zero magnetic field at 27 K. The nanometer-size surface modifications between 2 and 50 nm, especially layered etching, of the prepared BSCCO films were successfully performed by using a STM in air. |
