Xps (x ray photoelectron spectroscopy)Zaahir Salam
The document provides an overview of X-ray photoelectron spectroscopy (XPS) technology. XPS works by irradiating a sample surface with x-rays and measuring the kinetic energy and number of electrons that escape from the top 1-10 nm of the material. This allows one to determine the sample's elemental composition and chemical/electronic states. Key aspects discussed include the use of ultra-high vacuum conditions to prevent surface contamination and allow for accurate analysis. Characteristic XPS spectra are produced that contain peaks corresponding to different elemental binding energies.
My visit to auckland university (Ethan van Wijk)willowbank
I visited the Auckland University Nanomechanics lab where I toured their Scanning Electron Microscope, X-ray photoelectron spectroscopy equipment, and Biomechanics lab. The lab is run by Dr. Michelle Dickinson, a Senior Lecturer in the Department of Chemical and Materials Engineering.
X-ray photoelectron spectroscopy (XPS) is a surface-sensitive technique that uses X-rays to eject electrons from a material's surface and measure their kinetic energy to determine the elemental composition and chemical states. Kai Siegbahn developed XPS in the 1950s and won the Nobel Prize for his work. A study used XPS to analyze the surface chemistry of langasite crystals before and after vacuum annealing, finding that higher-temperature annealing reduced the surface concentration of gallium. XPS provides quantitative and chemical state information from the top 10-100 Angstroms of a surface.

The document describes the capabilities of an X-ray photoelectron spectroscopy (XPS) instrument called the K-Alpha XPS from Thermo Scientific. The K-Alpha provides high throughput analysis with micrometer-scale spatial resolution. It features an aluminum anode X-ray source for high chemical state resolution and a focused ion beam for sample cleaning and depth profiling. The document outlines how XPS can be used to identify elements, quantify elemental composition, and determine chemical bonding states at surfaces.
The document provides an overview of X-ray Photoelectron Spectroscopy (XPS) as a surface analysis technique. It describes how XPS works based on the photoelectric effect, and how it can be used to identify elements, chemical states, and compounds present on material surfaces. The key components of an XPS instrument are also outlined.
