発明の名称 (英語) Inverse photoemission spectroscopy apparatus
発明の概要(英語) (TW201546438)
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.
特許請求の範囲(英語) [claim1]
1. Kinds of reversed light electric firing dispersion of light installments, its characteristic lies, it is in the assay illumination electron beam, when examines in the assay the electron relaxes to the empty state position produces the light;
And includes: The electron produces the department, it has illumination in the electron of assay;
The wave length choice department, its choice is produced in the light to have the light of specific wave length by the assay;
The light detector, its examination is chosen the light of department choice by wave length;
And condensation optical system, its disposition between assays and light detectors;
And the electron produces the department to contain the yttrium oxide as the thermoelectron release material.
[claim2]
2. Like request 1 reversed light electric firing dispersion of light installment, the light detector contained to having the light of 400nm above wave length does not have the electro-optic of transformation department date of blind sensitivity.
[claim3]
3. Like request 2 reversed light electric firing dispersion of light installment, the electro-optic of transformation department date blind contained to elect from containing electro-optic of transformation material cesium iodide, cesium tellurium and nitrided gallium group.
[claim4]
4. Like request item 1 to threes any reversed light electric firing dispersion of light installment, the condensation optical system includes: The collimating lens, it is to produce the light to transform way of the parallel light by the assay, disposes between the assay and wave length choice departments;
