Maria Guadalupe del Rocio Herrera Salazar

During her studies, María researched and developed a novel fabrication route for nanostructures fabrication by hole-mask colloidal lithography (HMCL). She created an atomic version of a pinhole by HMCL, and which angled evaporation is not required for complex nanostructures fabrication, using a structured intersection mask with a target shape in the micrometer scale to obtain replicas of a pattern on a nanometer scale, showing an experimental reduction factor superior to 10 000. Supplementary experiments were carried out using electron beam lithography to avoid the limited surface area at the bottom of etched holes in hole-masks, confirming the successful implementation of atomic pinhole cameras. Besides, she presents the fabrication of two functional plasmonic nanostructures by traditional HMCL.

The successful development and implementation of a novel fabrication route open new opportunities for research and increase the potential applicability of HMCL. Different types of plasmonic nanostructures can be fabricated over large areas for improvements in the plasmonic field, and others.  

The PhD degree was completed at the Interdisciplinary Nanoscience Center (iNANO), Faculty of Natural Sciences, Aarhus University.
