Surface morphology of continuous heteroepitaxial diamond layers on β-SiC (001) has been characterized by various methods. From surface normal SEM images, the surface was so smooth that crystal boundaries were not clearly observed, but in AFM and Normarski optical microscope images, shallow gaps supposed to be remnant boundaries and wrinkles on the surfaces were observed. On the other hand, isolated (001) surfaces before coalescence had no wrinkles and were smoother than the surface of continuous heteroepitaxial films. The wrinkles observed only on the continuous heteroepitaxial film are considered to be formed by strain caused by coalescence, and raise the new problem of heteroepitaxy when the degree of orientation is improved.
