Preparative methods

We combine electrochemical techniques, surface chemistry, and atomic layer deposition (ALD) to create novel, complex nanostructures with well-defined geometry and tunable structural parameters.

Electrode surfaces

ChemElectroChem 2018 issue 9 cover

ChemElectroChem cover (RSC)

We investigate systematically how increases in the specific surface area of a nanoporous electrode are reflected in the current density.

Photovoltaics

Ignacio's ETA solar cell cross-section

Micrograph: Minguez Bacho

We study how the efficiency of ‘extremely thin absorber’ (ETA) solar cells is affected by the thickness of the light absorbing layer and the other geometric parameters of the nanostructured semiconductor junction.

We create ordered arrays of elongated magnetic nanostructures for data storage application. By introducing structural irregularities along the axis of the structures, we aim to be able to store, read and write many bits of information per object.

Surface chemistry

We adsorb reactive molecules to solid surfaces, either for the purpose of designing reaction cycles for ALD, or for performing redox reactions at the solid/liquid interface.
