Résumé
Un résumé de nos connaissances théoriques actuelles sur les dislocations et leurs crans est suivi d'une discussion des différents aspects des effets de charge dans les cristaux purs ou dopés. On compare les conclusions avec certaines des plus récentes données expérimentales. Finalement, on résume la théorie et les expériences sur la tension critique de cisaillement dans ces solides.


Abstract
A summary of our present theoretical knowledge of the structure of dislocations and of their jogs is followed by a discussion of the various aspects of charge effects in nominally pure and in doped crystals. The conclusions are then compared with some of the more recent experimental data. Finally a resume is given of the theory and experiments concerning the influence of impurities on the critical shear stress in these solids.
