Abstract

The charged state of atoms in layered cation-substituted disulfides CuCr1−xVxS2 (x = 0−0.4) was studied using X-ray photoelectron spectroscopy. The study was performed with polycrystalline powder and ceramic samples of chromium-copper disulfides. CuCr1−xVxS2 samples were shown to comprise differently charged atoms of chromium, copper and vanadium, the charged state of which varies with the concentration of vanadium cations (x).
