Proton distribution visualization in perovskite nickelate devices utilizing nanofocused X-rays

Ivan A. Zaluzhnyy, Peter O. Sprau, Richard Tran +17

We use a 30-nm x-ray beam to study the spatially resolved properties of a SmNiO${}_3$-based nanodevice that is doped with protons. The x-ray absorption spectra supported by density-f…
