Determination of the Burgers vector of a dislocation from equal-thickness fringes observed with a plane wave of X-rays

Abstract

This note reports on the observation of the appearance of singularity in the equal-thickness fringes at the outcrop of a dislocation in silicon observed with a plane-wave of X-rays and proposes a method of determining directly the magnitude and sense of the Burgers vector from the number of the extra half lines of the fringes.
