摘要：
Dislocation contrast in silicon carbide has been examined using white-radiation synchrotron topography. It was found that, in the case of dislocation bundles, the existing theory had to be extended to take into account the overlapping of dislocation strain fields. With this modification, the agreement between theory and observation is greatly improved.
