Mesoporous hosts for electrodeposition of semiconductors

Lead Research Organisation: University of Southampton
Department Name: School of Chemistry

Abstract

This student is to carry out research on the production mesoporous silica substrates for use as electrodeposition templates. Key targets are the integration of porous materials into microfabricated structures and the control of the surfaces of the porous materials to provide beneficial interactions with the semiconductors. There are significant opportunities to develop new methods to control pore size, orientation and chemistry. Materials characterisation will also feature strongly, including in-house facilities and experiments at central facilities such as the Diamond synchrotron.

Description With the focus of this award being the dynamics present during electrodeposition, we have achieved the creation of a reliable experimental setup for the observation of such systems. This required the design of suitable electrochemical cells, that could be used on a neutron or X-ray beam line, allowing for the real-time investigation of electrochemical dynamics whilst retaining realistic deposition conditions. In addition, a routine for the treatment of large datasets resulting from these experiments was developed and applied. This enabled us to produce detailed description of the structural evolution of aligned silica pores, which is in preparation to being published. A preliminary study on a model system gave rise to structural limitations during electrodeposition, which are relevant for the deposition into nanotemplates.
Exploitation Route The routines and experimental environments established with this funding can be used for future studies aimed at even deeper insight into electrochemical dynamics. This could lead to a more detailed and accurate description of the underlying mechanisms.
