Dr. Worawat Meevasana and Dr. Narong Chanlek from Suranaree University of Technology recently gave a talk on the “XPS and other photoemission techniques/application” at a NANO Talk session at NANOTEC.
The talk focused on the history and basic principle of XPS, examples of XPS spectra and their information, and aspects of instrumentation and proper measurement.
“X-ray photoelectron (or photoemission) spectroscopy (XPS) is one of classic techniques, yet still quite powerful for analysis of chemical/ elemental composition” said Dr. Worawat. “In the past few decades, many techniques based on XPS are developed for research applications including analysis of chemical reaction and fast dynamic (e.g. picosec to femtosec regime), element-resolved microscopy/spectroscopy, and detailed electronic structure of materials (e.g. momentum-resolved with high energy resolution); hence, photoemission techniques have been ones of desired tools for many frontier research nowadays”.
Dr. Narong talk was on “Beamline 3.2a: Photoemission Electron Spectroscopy”. His talk focused on basic principle and experiment, Beamline 3.2a, applications, and how researchers can apply to use the beamline. Dr. Narong encourages researchers to submit technical proposal to use Beamline 3.2a as he sees it as a developmental tool to expanding research knowledge.
NANO Talk is a monthly public forum organized by NANOTEC for researchers and visiting professors to exchange knowledge and be updated on technology trends. Visiting professors to Thailand are encouraged to participate.
