An electron and X-ray diffraction investigation of Ni1+xTe2 and Ni1+xSe2 Cdl2/NiAs type solid solution phases
Abstract
<p>The reported wide-range nonstoichiometric Ni<sub>1+x</sub>Te<sub>2</sub>, 0 ≤ × ≤0.83, and Ni<sub>1+x</sub>Se<sub>2</sub>, 0.57 ≤×≤0.92, CdI<sub>2</sub>/NiAs structure type solid solution fields have been carefully reinvestigated via electron and X-ray powder diffraction to search for evidence of Ni/vacancy ordering and superstructure phases. In the case of telluride, evidence is thereby found for a Ni<sub>3</sub>Te<sub>4</sub> superstructure phase attempting to condense out at × ̃ 0.5 while, in the case of selenide, three quite distinct phases have been identified within the Ni<sub>1+x</sub>Se<sub>2</sub> solid solution field. An intriguing characteristic honeycomb diffuse-intensity distribution has also been observed across the solid solution field in the case of the Ni<sub>1+x</sub>Te<sub>2</sub> system. Its presence has been attributed to low frequency phonon modes along certain very specific directions of reciprocal space.</p>
