発明の名称 (英語) INVERSE PHOTOELECTRON SPECTROSCOPY DEVICE NEW
発明の概要(英語) An inverse photoelectron spectroscopy device (1) radiates an electron beam at low energy to a sample (40) and detects light generated when electrons in the sample relax to an unoccupied level. The inverse photoelectron spectroscopy device (1) is provided with an electron generating part (10) for generating electrons radiated to the sample (40), a wavelength selecting part (90) for selecting light having a specific wavelength from light generated by the sample (40), a photodetector (100) for detecting the light selected by the wavelength selecting part (90), and a condensing optical system (80) disposed between the sample (40) and the photodetector (100). The electron generating part (10) includes yttrium oxide as a thermionic emission material.
