MATRIX-METHOD FOR THE X-RAY PECKING CURVE SIMULATION

A matrix representation is developed for the solution of the Takagi-Ta upin equations of x-ray diffraction. By the virtue of its unimodular p roperty, the solution matrix substantially reduces the calculation tim e for the superlattice (SL) structure with a large periodicity. Also, the simplified form of the solution makes it easier to understand and quantify the inherent properties of the x-ray diffraction such as the interference fringes and the SL peaks.
