Le but de ce travail est de comparer les résultats de caractérisation des défauts profonds dans le silicium amorphe hydrogéné(a-Si : H) intrinsèque obtenus par la méthode de photo-courant constant en régime périodique (AC-CPM) et en régime continu(DC-CPM). Pour cette raison, nous avons développé un programme de simulation qui tient en compte toutes les transitionsoptiques possibles, a savoir les transitions optiques directes entre les états occupés et la bande de conduction et les transitionsoptiques indirectes entre la bande de valence ou la queue de bande de valence et les états non occupés suivie par des émissionsthermiques convenables. Nous présentons ainsi la différence observée concernant le coefficient d’absorption optique et ladensi...
