The great theoretical and practical interest of these layers has, it is well known, given rise to many investigations from Faraday onwards. Within the necessarily restricted limits of this study, we shall approach the problem more particularly from the point of view of: - their production; - their use in electron microscopy. A critical appraisal is made, in the light of present-day knowledge, based on our personal experience and on an extensive bibliography which we have collected on the subject. (author) [French] Le present travail concerne la technique des couches minces obtenues par evaporation sous vide, dans le domaine d'epaisseur qui s'etend de quelques couches monoatomiques a plusieurs centaines d'angstroms. L'interet theorique et pratique considerable de ces couches a suscite, comme on sait, de nombreux travaux depuis Faraday. Dans le cadre necessairement restreint de cette these, nous aborderons plus particulierement le point de vue de: - leur obtention; - leur utilisation en microscopie electronique. Il s'agit d'une mise au point critique, a la lumiere des connaissances actuelles, appuyee sur notre experience personnelle et sur une importante bibliographie, qu'il nous a ete donne de reunir a ce sujet.
