Determination of surface composition by X-ray photoelectron spectroscopy taking into account elastic photoelectron collisions.
It is now well known that elastic photoelectron scattering in the surface region of solids cannot be ignored in the mathematical formalism of quantitative XPS. Elastic collisions may increase or decrease the photoelectron signal intensity, depending on the experimental configuration. Consequently, it is advisable to take into account these effects in calculations of the surface composition. In ...
متن کاملVertical Phase Separation in Poly(3-hexylthiophene): Fullerene Derivative Blends and its Advantage for Inverted Structure Solar Cells
Amethodwhichenables the investigationof theburied interfaceswithoutaltering the properties of the polymer films is used to study vertical phase separation of spin-coated poly(3-hexylthiophene) (P3HT):fullerene derivative blends. X-ray photoelectron spectroscopy (XPS) and atomic force microscopy (AFM) analysis reveals the P3HT enrichment at the free (air) surfaces and abundanceof fullerene deriv...
متن کاملX - Ray Photoelectron Spectroscopy of Silicate Glasses
X-ray photoelectron spectroscopy (XPS) is a powerful technique capable of providing unique information about the structural chemistry of glasses. However, inappropriate procedures for the preparation of sample surfaces or the lack of reliable methods to overcome electrostatic charging effects during analysis of dielectric materials can cause spurious features to be introduced or intrinsic featu...
متن کاملQuantitative characterization of DNA films by X-ray photoelectron spectroscopy.
We describe the use of self-assembled films of thiolated (dT)25 single-stranded DNA (ssDNA) on gold as a model system for quantitative characterization of DNA films by X-ray photoelectron spectroscopy (XPS). We evaluate the applicability of a uniform and homogeneous overlayer-substrate model for data analysis, examine model parameters used to describe DNA films (e.g., density and electron atten...
متن کاملSurface Characterization of Carbon Materials by X-ray Photoelectron Spectroscopy
Surface physicochemical properties are sensitive to preparation techniques, including physical and chemical treatments. Thus, surface treatments could induce significant changes in the surface modification of several materials. From its earliest days, X-ray photoelectron spectroscopy (XPS) was widely used as a powerful tool for understanding the nature of many different types of surfaces. Over ...
