| Outline of Final Research Achievements |
Our research group has developed an ultimate measurement method that has both the time resolution of a subcycle (within a cycle of an electric field) and a spatial resolution comparable to that of scanning tunneling microscopy (STM) by combining cutting-edge technology in quantum optics with STM. We succeeded in visualizing the ultrahigh-speed movement of electrons optically excited in C60 thin films and the movement of excitons in WS2/WSe2 structures at picosecond and nanometer resolutions for the first time in the world. In addition, we have realized time-resolved STM with the world’s highest time resolution (< 30fs) using a mid-infrared electric field to observe the real-space photoinduced nonequilibrium dynamics in MoTe2. Our method also explored core technologies that can generate a new scientific field by combining the systems we developed, for example, a time-resolved measurement method in which the condition of specimens is controlled coherently.
