STUDY OF ANALYSIS TECHNIQUES OF NANO STRUCTURED CARBON MATERIALS BY TRANSMISSION ELECTRON MICROSCOPY AND IMAGE PROCESSING

摘要

This study is aim at development of analysis methods of nano structure of materials by transmission electron microscopy (TEM) combined with image analysis. Recently, TEM techniques progress and samples can be observed atomic level. Selected area electron diffraction (SAD) which is one of the transmission electron microscopy techniques is difficult to apply to nano sized area. 2 dimensional fast Fourier transform (2D-FFT) was used for structural analysis of small area of carbon materials. In this study, we try to prove that the 2DFFT gives comparable result with SAD and useful for nano structured carbons.
