The diamond film was annealed in contact with Mn and Fe at 900-1000 degrees C for 0.5-20 h. After annealing the sample was cleaned by acid and was rinsed in acetone. The cleaned surface was observed by scanning electron microscopy under a secondary electron mode. A clear image of the etch pattern appeared on the flattened diamond him surface from the reaction with the metals. The detailed microstructural features in the etch patterns were correlated to those on the as-grown surface. The image contrast in the etch pattern was related to the local defect density: the more defective region appeared darker. The origin of image contrast on the etched surface was discussed.
