Porous thin film metrology

Many applications of mesoporous thin film architectures, including sensors, (photo)catalysis, photovoltaics, optical coatings and protective barriers are directly affected by structural properties, which include high surface area, surface functionalisation, and bicontinuous percolation paths on the 10nm length scale.

Although porosimetry of bulk materials via sorption techniques is common practice, the characterisation of thin mesoporous films with small sample volumes remains a challenge. In our group, we have developed a number of suitable characterisation techniques towards the reliable structural characterisation of mesoporous films, including one of the most advanced platforms for ellipsometry.
