Abstract :
Electron and X-ray diffractometry visualize atoms in severely stressed single-crystal silicon and help analyze the resulting phase transformations. Massively parallel computers simulate both diffraction techniques. We study these phase transitions with a number of simulation techniques. We calculate the position of the atoms in the material during the process and display atomic images of the crystal structure as a function of time. Simulated diffraction patterns enable us to follow structural transformations more easily. In addition, we have developed several diagnostic imaging techniques that aid the analysis of phase transformations: the pair-correlation function, bar-code plotting, ring statistics and subvolume visualization
