講題: To explore nano world and material science by X-ray nano probe at Taiwan photon source
摘要: Introduction to fundamental and technic aspects of the particularity of Taiwan Photon Source and apply X-ray nanoprobe to scientific research. In this talk, that will show some experimental cases like the X-ray fluorescence spectroscopy (for the analysis in the depth-of-field distribution of elements), extended X-ray absorption spectroscopy (for the analysis in the electronic configuration and the atomic or molecular bonding length), excitation X-ray fluorescence spectroscopy (for the analysis in the recombination and transport of carriers), in-phase scanning X-ray imageology (the Fourier phase transform calculation can improve the space resolution down to 3nm to 5nm, and detect the stress distribution inside the nanostructures). Moreover, the in-situ electrical testing system with 13 channels has been developed as well. It can be used to the in-situ measurement on the properties of semiconductor and optoelectronic devices when they are under operation.
