Inventor: HEIDEMANN ROLF DR
IPC: H04B10/67

Title: Process to examine monocrystalline material
Inventor: SCHNEIDER JOCHEN PROF DR
IPC: G01N23/207
Filed: 1991-07-23
Abstract: When monocrystalline structures are mfd. or processed it is important to determine deviations from the ideal values of density and average spreading of impure phases.  Novelty is that discrete sectors of the crystal are subjected to wave or particle beams, the dispersion of these beams is measured under Bragg conditions and the statistical Debye-Waller factors are automatically determined for different sample thicknesses with high resolution and flexibility in relation to wavelength changes. The beam incidence angle on the diffraction network level is varied and a measurement made of the reflection power by means of photon and particle detectors respectively to determine the integral reflection power R(int) and the sample is rotated about an axis which is vertical in relation to the network level resulting in a variation of the sample thickness. The value R(int) is determined in relation to the sample thickness, the static Debye-Weller factor is determined from the relationship measured, adjusted to a theoretical function. By measuring several orders of diffraction the density, number and average spread of the impurities is determined.
