BPN501: Patterned Contact Printing with Monolayer for Aligned Nanowire Arrays

Project ID BPN501

Abstract Large-area, patterned printing of nanowires by using fluorinated self-assembled monolayers (SAM) as the resist layer is demonstrated. By projecting a light pattern on the surface of the monolayer-resist in an oxygen rich environment, sticky and non-sticky regions on the surface are directly defined in a single-step process which then enables the highly specific and patterned transfer of the nanowires by the contact printing process, without the need for a subsequent lift-off step. This work demonstrates a simple route toward scalable, patterned printing of nanowires on substrates by utilizing light-tunable, nanoscale chemical interactions, and demonstrates the versatility of molecular monolayers for use as a resist layer.
