| Outline of Final Research Achievements |
By combining high energy resolution electron energy loss spectroscopy (EELS) and scanning transmission electron microscope (STEM), we succeeded in measuring spectra with reduced electron beam irradiation damage on organic materials. Especially, with the aloof beam method which can measure the spectrum without directly irradiating the sample with electons, the absorption spectrum in the infrared to ultraviolet region can be measured with almost no damage.
Spectral simulation was performed on the fine structures of the carbon K-shell absorption edge measured from organic crystals by first principle band calculation, and both agreed very well. As a result, new knowledge important for the state analysis of organic molecules could be obtained.
