Journal ArticleDOI
Cesium power: low Cs+ levels impart stability to perovskite solar cells
TL;DR: This study brings out the role of Cs+ to be of paramount significance to further engineer the composition and improve device performances.
Journal ArticleDOI
Surface-modified CuO layer in size-stabilized single-phase Cu2O nanoparticles
TL;DR: In this article, the authors show that the stabilization of the cubic Cu2O nanophase is enhanced by the formation of a CuO surface layer of thickness ≈ 1.6 nm.
Journal ArticleDOI
Bimetallic Cu-Ni nanoparticles of varying composition (CuNi3, CuNi, Cu3Ni)
Jahangeer Ahmed,Kandalam V. Ramanujachary,Samuel E. Lofland,Anthony Furiato,Govind Gupta,S. M. Shivaprasad,Ashok K. Ganguli +6 more
TL;DR: In this paper, the first report of the synthesis of CuNi3 and Cu3Ni nanoparticles was presented, which showed nearly monodisperse and uniform nanoparticles of average grain size of 7 nm for the 1:1 alloy nanoparticles.
Journal ArticleDOI
Modifying the nanocrystalline characteristics: structure, size, and surface states of copper oxide thin films by high-energy heavy-ion irradiation
B. Balamurugan,Bodh Raj Mehta,D.K. Avasthi,Fouran Singh,Akhilesh K. Arora,M. Rajalakshmi,G. Raghavan,A.K. Tyagi,S. M. Shivaprasad +8 more
TL;DR: In this article, the effect of ion irradiation on nanocrystalline Cu2O thin films grown by the activated reactive evaporation technique was studied and the influence of dense electronic excitations on the structural and optical properties of the thin films was analyzed.
Journal ArticleDOI
Size dependence of core and valence binding energies in Pd nanoparticles: Interplay of quantum confinement and coordination reduction
TL;DR: In this article, an analysis of the electronic structure of Pd nanoparticles synthesized by inert gas evaporation technique is given, which provides a direct evidence of interplay of quantum confinement (a size effect) and coordination reduction (a surface effect).
