Figure 1
The structure of Tl2Te viewed in the direction ∼[301]. Two basic units, the planar layer A and the puckered layer B, are shown. Open circles indicate Tl atoms and filled circles indicate Te atoms. Only the Te net in layer A and the Tl net in layer B are shown. The position of the shear plane is marked by a dashed line in each unit. The shear vector between two Tl5Te3-like regions is also shown. |
