| Outline of Final Research Achievements |
By introducing two nanoscale probes inside a transmission electron microscope (TEM), we promoted to improve an electrical measurement method in TEM for evaluating of electrical and thermal properties. For example, to improve a space resolution and precision of an electrical resistivity measurement, we developed a new sharpened CNT probe welded to a top of W probe and a TEM specimen for supplying a constant current by using an electron lithography and a focused ion beam system (FIB). Moreover, we also developed a local temperature measurement method in TEM as a fundamental technique for thermal resistivity measurement in TEM by assembling a nanoscale thermocouple. By using the developed thermocouple, direct measurement of a temperature increase of specimen on heating by electron beam irradiation and measurement of phonon conduction in a heat radiation composite material could be successfully demonstrated.
