Résumé. 2014 Dans les films de a-Si: H pulvérisés, le contenu total en hydrogène et sa répartition sur les sites SiH, SiH2 ou H ’ varient avec la posthydrogénation. On constate que la concentration de liaisons libres reste constante. Ces résultats peuvent être expliqués par une diffusion préférentielle de l’hy-drogène à l’intérieur de la zone tissu, alors que les liaisons libres sont localisées dans la zone ilot. La photoconductivité est contrôlée par les défauts sans spin du tissu et décroît si le contenu relatif en sites SiH2 augmente. Abstract. 2014 Total hydrogen content and its distribution among SiH, SiH2 and other H ’ sites of sputtered a-Si: H films vary after posthydrogenation but the dangling bond concentrations remain constant.
