Rev. B 34, 2910 (1986)]. This interpretation is further supported by a Cody law [Solar Energy Mater. 8, 231 (1982)] analysis for which no blueshift in the optical band ...
WebThe Tauc-law extrapolation has been recently applied to obtain the band gap of the hydro-genated amorphous silicon (a−Si:H) component of a−Si:Ha−SiNx:Halternating layer structures. An increase in the deduced band gap of the a−Si:Hlayer as its thickness is reduced below 30 Å has been attributed to quantum confinement in the a−Si:Hsublayers.
