Photoelectron diffraction investigation of the structure of the clean TiO2(110)(1×1) surface [PDF]

open access: yes, 2007
The surface relaxations of the rutile TiO2(110)(1×1) clean surface have been determined by O 1 s and Ti 2p3∕2 scanned-energy mode photoelectron diffraction. The results are in excellent agreement with recent low-energy electron diffraction (LEED) and

Gas-solid reaction based over one-micrometer thick stable perovskite films for efficient solar cells and modules

open access: yesNature Communications, 2018
Perovskite solar cells often suffer from poor uniformity and reproducibility especially in case of large area devices. Here Liu et al. developed a gas−solid reaction method that enables facile fabrication of over 1 µm thick perovskite films for solar ...

A Special Additive Enables All Cations and Anions Passivation for Stable Perovskite Solar Cells with Efficiency over 23%

open access: yesNano-Micro Letters, 2021
Passivating undercoordinated ions is an effective way to reduce the defect densities at the surface and grain boundaries (GBs) of perovskite materials for enhanced photovoltaic performance and stability of perovskite solar cells (PSCs).

Facile Construction of 2D/2D ZnIn2S4-Based Bifunctional Photocatalysts for H2 Production and Simultaneous Degradation of Rhodamine B and Tetracycline

open access: yesNanomaterials, 2023
A two-dimensional/two-dimensional (2D/2D) TiO2/ZnIn2S4 photocatalyst was reasonably proposed and constructed by a two-step oil bath-hydrothermal method. TiO2 nanosheets uniformly grown on the surface of ZnIn2S4 nanosheets and a synergetic effect between ...

Concentrator of laser energy for thin vapour cloud production near a surface [PDF]

open access: yes, 1998
A novel scheme is presented for production of a thin ($100$ cm$^2$) by pulsed laser ablation of a solid surface. Instead of dispersing the laser energy uniformly over the surface, a modified Fabry-Perot interferometer is employed to concentrate the laser
