Abstract The current study is concerned with the first principle investigations of the oxygenated MoS2 to explore the electronic and optical properties. We consider various oxygen concentrations (MoS2, MoS1.75O0.25, MoS1.5O0.5, MoSO) for the prediction of its impact on parameters using PBE-GGA approximation. A noticeable change in parameters has been observed in the visible regime with the introduction of oxygen content in the MoS2 structure. The results of the electronic properties suggest a string role of Mo d-states, S p-states, and O p-states which, however, show variations for various O concentrations near the Fermi level. In comparison to the absorption trend of pure MoS2, the optical absorption spectra show a blue shift in the visible range. The effect of oxygen can also be seen in the experimentally prepared MoS2 thin films as the variation of optical behavior can be seen. Refractive index decreases from ~2.5 to ~2. Similarly, absorption graphs show a lack of absorption phenomenon as the oxygen content increases. The role of oxygen brings appreciable changes in the optical parameters over the different energy ranges.

Observed Behavior

In this note we are communicating the results obtained on various samples of lanthanum-based cuprate in which Sr and Zn have been partially substituted for La and Cu, respectively over a range where the superconductivity is gradually destroyed. The decrease in T c is accompanied by a changeover from metallic to semiconducting-like resistance behavior occurring at lower temperatures. The observed behavior is related to the effective copper valence and the change in the oxygen content of the samples and the results are discussed in terms of a tentative phase diagram which would be necessary to examine the mechanism of superconductivity.
