Simulation de topographies en pose fixe par la méthode de Lang au moyen d'un ordinateur. Influence du vecteur de Burgers

A computer program is described which simulates section topographs of dislocations. It is shown that the contrast of the image is greatly modified when the direction, magnitude and sign of the Burgers vector of a given dislocation are varied and that it is now possible, by comparison of the simulation with the experiment, to determine quantitatively the Burgers vector of any straight dislocation in any crystal.
