【Abstract】 We are the first to report the realization of quasiperiodic amorphous semiconductor superlattices composed of alternating layers of a-Si:H and a-SiNx:H to form a Fibonacci sequence in which the ratio of incommensurate periods is equal to the golden mean T=(1+5^1/2)/2. In the present work new results of low-angle X-ray diffraction pattern with Lf = τLa + Lb= 148A are well consistent with a numerical calculation using formula Km,n = 2τLf-1 （mτ +n）, which further demonstrate the peculiarities of quasiperiodicity. From electrical measurements done along the film plane, the feature of temperature dependence of σd suggests that there are two transport pathes at different temperature region. We tentatively explain this phenomenon in terms of the different space charge density and mobility edge in two distinct building blocks A and B of quasiperiodic a-Si:H/a-SiNx:H super-lattices.更多还原
