| Outline of Final Research Achievements |
The purpose of this study is to make quantitative evaluation of the photo-induced local-expansion of the surface relief in thallium ternary compounds. The investigated samples exhibit micrometer order expansion with short response time at low pump beam power of about two orders less than the optical damage threshold. These results indicate that the thallium ternary compounds are promising materials for new light-driven systems. From the result of the simulated calculation for the photo-induced expansion, it is suggested that the local-expansion is due to small thermal conductivity in the thallium compounds. The electronic band structures of some thallium compounds display an abrupt change around the temperatures of the structural phase transitions. It is reasonable to suppose that the giant photo-induced expansion in the thallium ternary compounds is related to the change of physical properties by the structural phase transitions.
