“Spontaneous Formation of Core-Shell Nanoparticles of Au-SiO2 at the tip of Silicon Nanowires Revealed by Scanning Electron Microscopy at Very Low Voltages”

By Laura Zarraoa Sardón (Autonomous University of Madrid) and supervised by Álvaro San Paulo Hernando , Tenured Scientist at the Institute of Micro and Nanotechnology.

Abstract

The extraordinary imaging power potential of scanning electron microscopy when the electron beam hits the sample with very low energy (<1 keV) has been known for decades. However, only the latest generation instruments reach ultra high resolution (<1 nm) under these conditions. In this work, the structure of the tip os Si nanowires grown via the vapor-liquid-solid mechanism is investigated by applying this technique. We have discovered the spontaneous formation of gold-silica core-shell structures at the tip of the nanowires, demonstrating the exceptional potential of this technique for the study of low dimensional nanostructures.

Talk of Montserrat Calleja directed to students of fifth and sixth grade of primary school. This talk is part of the project “Scientists count” funded by the Spanish Foundation for Science and Technology (FECYT) and coordinated by the CSIC Delegation to the European Union, which in turn co-finances the General CSIC Foundation and the support of the European Research Council (ERC).

The Mas Awards were born in 2014 to give visibility and recognize female talent. In this fifth edition, Montserrat Calleja has been awarded in the Science category.
