摘要：

TaTe4 is a quasi-one-dimensional crystal which at room temperature displays a periodic lattice distortion associated with charge-density waves. In the present study the modulations were investigated by high resolution electron microscopy (HREM). Images recorded in the [210] orientation confirm the absence of a simple mirror plane normal to the c-axis in the tetragonal structure. A comparison of experimental and computed images supports the model for the modulated structure deduced by X-ray diffraction.
