Abstract : The microstructures of mercury-based cuprate thin films have been studied using a scanning electron microscope and an energy dispersive x-ray spectrometer. Besides rough surface, several types of defects including HgCaO2 phase are identified on those films made using a slow temperature ramping Hg-vapor annealing process. By ramping the sample temperature rapidly to the annealing temperature, the surface morphology of the film is significantly improved and the impurity phases, especially the HgCaO2 phase, are effectively reduced.
