| Outline of Final Research Achievements |
This research aims to develop a new technique to measure a surface-local thermodynamic temperature (absolute temperature) without contact to the object and any calibration, that is, Fermi-Dirac distribution measurement of electrons in solid surface. For the purpose of developing this temperature measurement technology, the energy distribution of electrons measured by photoelectron spectroscopy on the surface of Au (110) single crystal cooled with liquid nitrogen was fitted with Fermi-Dirac distribution in accuracy of ± 2.1 K. Successful determination of thermodynamic temperature was performed consistently with sensor temperature.
