Raman spectrum of iro2
WebbThe spectroscopy mode of the electric force microscope (EFM) was used to study the variation of the local electric force gradients above CVD-grown thin films of iridium oxide field emitters. The spacing, radius, and morphology of the nanoprotrusions were observed to change significantly within the sample. In this research, we present the first EFM … WebbThe structure of IrO 2 during the oxygen evolution reaction (OER) was studied by operando X-ray absorption spectroscopy (XAS) at the Ir L 3 -edge to gain insight into the …
