Photoconductivity‐Driven Quantum Efficiency Gain in Inorganic Ruddlesden‐Popper Layered Cs2PbBr2I2 Perovskite Photodetector for Visible Light Detection

open access: yesAdvanced Functional Materials, EarlyView.
Rational halogen mixing strategy was employed to shift the bandgap of Cs2PbBr2I2 from ultraviolet to visible region, enabling first realization of a visible‐light photodetector with this 2D layered Ruddlesden‐Popper perovskite material. Under illumination, light‐induced internal field forms and drives trap‐mediated persistent photoconductivity ...

X-ray photoelectron spectroscopy

Vacuum, 1994
It is now some twenty-five years since the first commercial X-ray photoelectron spectrometers appeared in the market place and the intervening years have seen the technique develop into a mature, if not altogether routine, surface analytical method. However, the scientific roots of the method arc much older, the photoelectric effect was discovered by ...

X-ray photoelectron spectroscopy [PDF]

open access: yes
The interaction of photon and the electron goes back to the early part of 19th century emanating from the photo-electric effect depicted by none other than Albert Einstein (Ref 1) described in 1905, and the redistribution of kinetic energy resulting from

X-ray Photoelectron Spectroscopy

2008
X-Ray photoelectron spectroscopy is a highly surface sensitive technique, which can provide information on composition, binding and functionality of polymers at the surface. The aspect of information depth and surface charging is discussed as well as quantification and data interpretation.

X-ray photoelectron spectroscopy using hard X-rays

Journal of Electron Spectroscopy and Related Phenomena, 2010
Abstract Hard X-ray photoelectron spectroscopy (HAXPES or HXPS), using hard (2–15 keV) X-rays for excitation and high energy resolution, has shown a spectacular development recently, due to its capability for providing an insight into the bulk electronic structure of solids and the chemical composition of buried layers and interfaces lying at depths ...
