An analysis of the model of Cody et al. explaining the disorder"optical-absorption-edge relationships for hydrogenerated amorphous silicon is presented here. In this analysis, certain disorder-related parameters are defined better in order to facilitate the understanding of the Cody model. Although the present study clarifies some aspects of the model, some questions relating to the topological-disorder"hydrogen-content"thermal-disorder interrelationships remain unanswered. It may be noted here that none of the calculations in the present work are speculative, but are based on well-accepted theories such as the Cody model and their application to hydrogenated amorphous silicon.
