| Outline of Final Research Achievements |
Direct writing techniques of metals and semiconductors using femtosecond laser pulse-induced thermochemical reduction have been developed. When the femtosecond laser pulses were focused into the raw materials such as metal oxide nanoparticle solutions and metal complex solutions, the metals and semiconductors were precipitated at around the focal spot of the femtosecond laser pulses, resulting that two and three dimensional microstructures were directly written in air. Finally, the thermocouples consisting of Cu-Ni micropatterns with different Seebeck coefficients were developed by controlling the reduction degree of the metals.
