Electron Speckle and Higher-Order Correlation Functions from Amorphous Thin Films
Published online by Cambridge University Press: 10 February 2011
Abstract
We obtain valuable information about medium-range order in amorphous semiconductors from variable coherence microscopy, a new quantitative approach to TEM. The technique reveals three-body and higher-order atomic correlation functions, which are sensitive to medium-range order. Preliminary experimental evidence for structural changes on annealing has been found for amorphous semiconductor films, with pronounced medium-range order seen only in unannealed films.
