This talk presents an overview of  recent work on the nanomanufacturing of flexible electronics and energy systems.  By tightly focusing pulsed laser radiation to nanometric dimensions we have been able to induce materials modification processes at extremely small scales. Applications in nanoprocessing, nanomachining, nanolithography and nanodeposition have been demonstrated. Interactions of pulsed  laser  radiation  with  nanostructures  are  investigated  and  shown  to  substantially improve device performance. New concepts have been introduced for the high throughput, directed growth and assembly of nanostructures.

Maskless  fabrication  of  functional  devices  on  flexible  substrates  has  been conducted by utilizing nanoparticles in conjunction with laser processing and high-resolution nanoimprinting. High-performance electronics and solar cells have been  realized  on  flexible  substrates.  Laser  processing  combined  with  high  throughput printing and imprinting has the potential to enable an integrated approach for the scalable manufacturing of optimized energy systems.

Costas P. Grigoropoulos received his Diploma Degrees in Naval Architecture and Marine Engineering (1978), and in Mechanical Engineering (1980) from the National Technical University of Athens, Greece. He holds a M.Sc. degree (1983), and a Ph.D. (1986), both in Mechanical Engineering from Columbia University. He joined the faculty of the Department of Mechanical Engineering at the University of California at Berkeley in 1990. His current research interests are in micro/nano engineering,  laser  materials  processing,  laser-biomaterial  interactions, manufacture of flexible electronics, microscale energy sources, microscale and  nanoscale transport. His laboratory is engaged in the development of new methods for the manufacture of functional nanoscale devices.
