Laser-Material InteractionsLaser-induced process for flexible electronics

 Laser is one of the most useful tools for solving  the temperature issues of flexible substrates (only enduring 100 Celcius for PET), which hinders high performance flexible electronics and materials. Laser can focus high thermal energy to a localized region in extremely short time (nsec ~ μsec) while minimizing thermal damage on the substrates. By using light-reacting layer and laser irradiation through transparent sacrificial substrate, high performance flexible oxide TFT, flexible piezoelectric nanogenerator and flexible memory have been tranferred from bulk substrate to plastic substrates. We named this technolog as Inorganic Laser Lift-off (ILLO), providing new breakthrough of inorganic-based high peformance flexible electronics.
