X-ray Photoelectron Spectroscopy (XPS) Instrument Explained: Hardware Demo

In this video, I walk you through an X-ray Photoelectron Spectroscopy (XPS) instrument and explain how each hardware component works. XPS is one of the most powerful surface analysis techniques in physics, chemistry and materials science. It tells us which elements are present on a material’s surface and what their chemical states are. In this video you will learn: What X-ray Photoelectron Spectroscopy (XPS) is and the photoelectric effect behind it The X-ray source and how it excites the sample Why XPS needs an ultra-high vacuum (UHV) system The sample holder, loading chamber, and transfer mechanism The electron energy analyzer and detector How the measured binding energy gives us the spectrum How to read a basic XPS spectrum Who is this video for? School and college students, M.Sc. and PhD researchers, and anyone curious about surface characterization techniques. #XPS #XRayPhotoelectronSpectroscopy #SurfaceScience #MaterialsCharacterization #Physics #PhotoelectricEffect #Spectroscopy #DeepakMarwal
