Chromatic Index of Signed Generalized Book Graphs and Signed Complete Graphs

Deepak Sehrawat, Rohit

A signed graph $(G, I ¨ )$ consists of a graph $G$ and the signature $I ¨ : E (G) \to {+ 1, - 1}$ . An incidence of $G$ is a pair $(v, e)$ , where $v$ is one of the end vertices of a…

(111) Facet-engineered SnO2 as Electron Transport Layer for Efficient and Stable Triple-Cation Perovskite Solar Cells

Keshav Kumar Sharma, Rohit, Sochannao Machinao +1

We report the (111) facet-engineered cubic phase SnO2 (C-SnO2) as a novel electron transport layer (ETL) for triple-cation mixed-halide Cs0.05(FA0.83MA0.17)0.95Pb(I0.83Br0.17)3 per…
