High efficiency bi-harvesting light/vibration energy using piezoelectric zinc oxide nanorods for dye decomposition
Jiangping Ma,Jing Ren,Yanmin Jia,Zheng Wu,Zheng Wu,Lin Chen,Neale O. Haugen,Haitao Huang,Yongsheng Liu +8 more
TL;DR: In this paper, the photo-/piezo-bi-catalysis of ZnO nanorods in dye decomposition can be attributed to that the piezoelectric potential formed in piezocatalysis process can help separate the photogenerated electron-hole pairs.

Enhanced Gas Sensing Properties of Spin-coated Na-doped ZnO Nanostructured Films.
TL;DR: The wrinkle net-work nanostructured Na-doped ZnO film shows an unusually sensitivity for CO2 gas at room temperature, and enhanced sensing properties are ascribed to high surface-to-volume ratio, hoping effect, and the increase of O- vacancies density according to Kroger VinK effect.

Excellent visible-light driven photocatalyst of (Al, Ni) co-doped ZnO structures for organic dye degradation
I. Neelakanta Reddy,Ch. Venkata Reddy,Jaesool Shim,Bhargav Akkinepally,Migyung Cho,Kisoo Yoo,Dongseob Kim +6 more
TL;DR: In this article, two co-doped ZnO nanostructures were synthesized by a simple ball-milling method and the results showed that 2%Al-2%Ni-ZnO was the most active photocatalysts for pollutant degradation, effecting 100% removal of methyl orange and Congo red under visible-light illumination.

X-ray photoelectron spectroscopy and auger electron spectroscopy studies of Al-doped ZnO films
TL;DR: In this article, the chemical state of oxygen, aluminum and zinc in Al-doped ZnO (ZAO) films was investigated by X-ray photoelectron spectroscopy (XPS), as well as the transition zone of the film-to-substrate, by auger electron spectrography (AES), showing that zinc remains mostly in the formal valence states of Zn2+.

Blueshift of optical band gap in ZnO thin films grown by metal-organic chemical-vapor deposition
TL;DR: The optical band gap of ZnO thin films deposited on fused quartz by metal-organic chemical-vapor deposition was studied in this article, where X-ray diffraction measurements showed that samples deposited at low temperatures (<450°C) consisted of amorphous and crystalline phases.

Core-level binding-energy shifts at surfaces and in solids
TL;DR: A review of core-level binding energy shifts observed in photoelectron spectroscopy can be found in this paper, where the authors focus on shifts since most of the chemical and physical insights provided by core levels are derived not from the core energies themselves but from shifts they exhibit.
