| Abstract: | Whem the nonradiative recombination of carriers and the quantum size effect in the a-Si:H/a-SiN_x:H superlattice films have are studied by photoacoustic techonlogy,it is discovered that the nonradiative recombination of carriers is related to the defects in the superlattice film and the optical gap of the film increases with the decrease of width of the well. |
