    • Abstract

       

      Lattice imaging technique has been used to study an unknown high period polytype structure of SiC. A known structure like 6H has been studied by tilted beam two-dimensional images to determine optimum conditions for deriving structural information. The technique has then been used to determine a new structure (411R and its intergrowth structures), and the lattice imaging technique as a tool for structural investigation has been critically evaluated.
