"Femtosecond Laser Induced Forward Transfer Techniques for the Deposition of Nanoscale, Transparent, and Solid-Phase Material."
Speaker: David Banks
Date: Wednesday 29th October 2008
Venue: Building 46, Lecture Theatre B
The Laser-Induced Forward Transfer (LIFT) technique offers a simple and versatile method of micron-scale patterning a variety of materials. In this talk, I will present results of recent work investigating whether the capabilities of LIFT can be extended by the use of femtosecond-duration pulses. In principle, ultrashort pulses should allow for the deposition of smaller structures and transfer of transparent materials or those displaying long-range order. We will demonstrate the deposition of 300 nm diameter structures, the smallest by LIFT to date, and transfer of transparent oxide and polymer films. Solid-phase transfer proves to be more challenging, but is also demonstrated through the use of multiple, spatially-shaped pulses.
