WebThis letter was not answered, and Frank did not think further about dislocations until he came to Bristol at Mott’s invitation after the war, when he read the paper by J. M. Burgers early in 1947 and realized that the question was answered, and that one should think in three dimensions instead of two. WebApr 1, 2007 · Dislocations in semiconductors can start to multiply at Frank Read sources. Since in the pre-yield region they are aligned along the 〈1. 1 0〉 directions, it is possible to calculate the energy of a bow-out analytically and to derive an expression for the stress necessary to activate a Frank Read source..

In materials science, a Frank–Read source is a mechanism explaining the generation of multiple dislocations in specific well-spaced slip planes in crystals when they are deformed. When a crystal is deformed, in order for slip to occur, dislocations must be generated in the material. This implies that, during … See more Charles Frank detailed the history of the discovery from his perspective in Proceedings of the Royal Society in 1980. In 1950 Charles Frank, who was then a research fellow in the physics department at the See more The Frank–Read source is a mechanism based on dislocation multiplication in a slip plane under shear stress. Consider a straight dislocation in a crystal slip plane with its two ends, A and B, pinned. If a shear stress $${\displaystyle \tau }$$ is … See more
