Optical and transport properties and electronic structure of nickel doped arsenic chalcogenides

► The paper reported electronic properties of doped and undoped Arsenic chalcogenide ► The reported properties investigated using FP-LAPW method in the framework of DFT. ► The paper is also reported optical and transport properties of As2X3 (X = S, Se). ► The reported DOS of As2X3(X = S, Se) excellent agreement with measurements using XPS.
