Structural defects of crystalline compounds affect the performance of devices based on such materials. A dislocation structure simulation method for crystalline compounds with intermediate values of dislocation densities is proposed (∼105–106 cm−2). The influence of various defects on shape of diffuse and coherent components of intensity distributions of X-ray scattering is shown. Probable dislocation reactions are considered at block boundaries and inside of crystals. Possible dislocation system as the set of complete 60°-dislocations and partial dislocations is investigated based on Krivoglaz kinematic theory with use of Monte Carlo method.
Key words: crystalline compounds, high-resolution X-ray diffractometry, defect structure, Monte Carlo method, rocking curves, reciprocal space maps.
