Abstract

Atomic resolution images of Ba_0.6K_0.4BiO₃ have been obtained at electron-dose levels of 10² e^-/Å² using a slow-scan CCD camera on a high-resolution electron microscope; at this dose level electron-beam damage can be avoided. The superconducting material is a clean perovskite without evidence for any distortions such as charge-density waves. At higher dose levels modulations appear which, from measurements of the desorbing species under low-energy electron radiation, are due to ionization damage and loss of oxygen.
