Transparent conductive thin films (TCO) are widely used in the manufacturing of both flat panel displays and solar cells two market segments which are rapidly developing in the last decade. TCO thin films allow the electrical contacting of large active areas that is largely transparent in the visible spectral range.

Hydrogenated amorphous silicon (a-Si:H) thin films have been considered for use in solar cell applications because of their significantly reduced cost compared to crystalline bulk silicon, however, their overall efficiency and stability are less than that of their bulk crystalline counterparts. Limited work has been performed on simultaneously solving the efficiency and stab...$28.00

This work demonstrates that ultrafast picosecond lasers provide the gentle touch and cold ablation required to remove metal films from ultra-thin polymer membranes without damaging the membrane substrate. Metal films of 10-100 nm in thickness are selectively removed from free-standing polymer membranes of thickness of 3 um. The metal is completely removed in a lift-off process, enabled by a single laser pulse (10-40 ps, 532 nm). No damage...$28.00

Plasmonic Devices Fabricated by Femtosecond Laser Nanowelding

Anming Hu, University of Waterloo; Waterloo ON Canada
Presented at ICALEO 2011
Laser nanowelding appears as a powerful tool for nanomanufaturing. We fabricate plasmonic devices with femtosecond laser irradiation with the aid of the near-field scanning optical microscopy (NSOM). NSOM is employed for both nanowelding and in-situ characterization. It is displayed that femtosecond laser irradiation induces a non-thermal ultrafast melting of metal nanomaterials, resulting in welding of Ag nanowires, nanoparticles and nanoplates. The laser-nanomaterial interaction and optical properties of joint nanomaterials are investigated by b...$28.00

Abstract: In this study, the fabrication of microfluidic chip containing a row of 198 micropillars was described. The chips were used to separate cells. The geometric deformation of micropillars in microfluidic chip on the PI and PMMA substrates micromachining was caused by cumulative heat during laser ablation...$28.00
