Abstract
An important concern in the deposition of thin microcrystalline silicon (μc-Si) films is to obtain the dynamic scaling exponent. We have analyzed the dynamic scaling exponent of μc-Si thin films on different substrates using surface profilometry. The
surface roughness of the thin microcrystalline silicon films and the different substrates both are shown and compared. The results reveals that the abnormal dynamic exponent of thin film on the stainless steel substrate account for shadow effect, and the dynamic exponents of thin films on the c-Si substrate and the glass substrate imply the change of growth mechanism with distance from center..
