Journal ArticleDOI
Elastic Scattering Corrections in AES and XPS. II. Estimating Attenuation Lengths and Conditions Required for their Valid Use in Overlayer/Substrate Experiments
Peter J. Cumpson,Martin P. Seah +1 more
TL;DR: In this article, the attenuation length is used to estimate the thickness of an overlayer in the presence of elastic scattering, and it is shown that using attenuation lengths eliminates most of the error due to elastic scattering without increasing the complexity of the quantification.
Journal ArticleDOI
Angle-resolved XPS and AES: depth-resolution limits and a general comparison of properties of depth-profile reconstruction methods
TL;DR: In this article, it was shown that the depth resolution in ARXPS is limited by signal-to-noise ratio, not the number of emission angles for which data is acquired, and that depth resolution can be improved by up to a factor of about 2 by confining the interval over which the CDP is reconstructed.
Journal ArticleDOI
The Thickogram: a method for easy film thickness measurement in XPS
TL;DR: In this article, a simple graphical method for measuring film thickness by XPS, called Thickogram, was described, which incorporates the effects of elastic scattering and can be used even when the film and substrate peaks have very different kinetic energies.
Journal ArticleDOI
Estimation of inelastic mean free paths for polymers and other organic materials - use of quantitative structure-property relationships
TL;DR: In this article, a quantitative structure-property relationship (QSPR) was proposed to estimate the IMFP of polymers and other organic materials from their structural properties, which can be applied across a range of organic structures for kinetic energies of ∼200-2000 eV.
Journal ArticleDOI
A three-dimensional Mn3O4 network supported on a nitrogenated graphene electrocatalyst for efficient oxygen reduction reaction in alkaline media
Santosh Kumar Bikkarolla,Fengjiao Yu,Wuzong Zhou,Paul Joseph,Peter J. Cumpson,Pagona Papakonstantinou +5 more
TL;DR: In this article, a three-dimensional, 3D, self-assembled Mn3O4 hierarchical network has been grown on nitrogen doped reduced graphene oxide (NrGO), by a facile and controllable electrodeposition process and its electrocatalytic performance for oxygen reduction reaction (ORR) has been assessed.
