Abstract
Experimental evidence for the existence of excitonic states in hydrogenated amorphous silicon is reviewed. It is shown that weakly coupled electron-hole pairs can be observed in spin-dependent recombination experiments up to room temperature. Details of the electron-hole interaction are discussed, and the role of excitonic states in the light-induced creation of metastable defects in amorphous silicon is examined.
