Structural investigation of the insulator-metal transition in NiS${}_{2-x}$Se${}_x$ compounds

Garam Han, Sungkyun Choi, Hwanbeom Cho +3

We report on a combined measurement of high-resolution x-ray diffraction on powder and Raman scattering on single crystalline NiS2-xSex samples that exhibit the insulator-metal tra…
