Description | We have studied nitrogen-doped silicon wafers (001) using triple-axis high-resolution X-ray diffraction (HRXRD). The reciprocal space intensity distributions from clusters, stacking faults and dislocation loops were modelled using the Krivoglaz theory and a continuum model of the defect deformation field. Good agreement of the theory with the experimental data was achieved for the model of dislocation loops. The symmetry of measured reciprocal space map determines the type of dislocation loops and from cross section we can determine their radius and concentration. These parameters were combined with the results from infrared absorption spectroscopy method. |
