High-resolution transmission electron microscopy (TEM) images show that the NaCl as well as the rhombohedral GBT and GST structures are observed along specific directions. From the TEM images, we suggest an atomic model and a phase transition mechanism by lattice distortion. (C) 2009 WILEY-VCH Verlag GmbH & Co.
