The DURIP program Variable-temperature Microwave Impedance Microscope with Light Stimulation for Research on Photo-induced Phase Transitions supported by ARO has been successfully completed. This novel apparatus will be the first scientific instrument that offers mesoscopic conductivity information with laser excitation under variable temperatures from 10 to 300 K. The innovative experimental investigations enabled by this system includes 1 Nanoscale coexisting phases in chalcogenide glasses 2 Light-driven versus temperature driven phase separation in transition metal oxides 3 Spatial distribution of photo-induced hidden states associated with charge-density waves. The research to be conducted based on this platform will provide significant amount of new knowledge on many advanced materials that are important for military applications in photo sensing and data storage.
