N2 - We find signatures of superconductivity at Tc=12 K in a molybdenum arsenide sample containing ∼4% of MoO2-δ impurity by weight. Below is a report on the electronic structure calculations, structures analyses, and thermodynamic and transport properties on Mo2As3, Mo5As4, and MoO2, in order to uncover the reasons for superconductivity for the sample that contains a mixture of these phases. The experimental and theoretical evidence suggest that superconductivity in the MoO2-δ phase is likely and may be caused by nesting-type fluctuations.
