Research

Research in the Page laboratory is focused on developing novel, sustainable synthetic routes to solid-state materials that have relevance to developing technologies. 

An integral component of our work is the emphasis that we place on using a broad array of characterization techniques to evaluate the structure and properties of the materials we make in order to derive correlations between the synthetic route, structure and composition, and physical properties, and using these correlations to optimize synthetic parameters and resulting properties.

Current research focuses on aqueous routes to metal oxide thin films with a range of properties and potential applications, from ionic conductivity to ferromagnetism.  Of particular recent interest, the group has been working on developing low-temperature aqueous routes to high quality amorphous dielectric insulators for the next generation of electronic devices.

As a member of the Center for Sustainable Materials Chemistry (CSMC), the Page group works with over twenty research groups across the country to expand the application of green routes to technologically relevant materials.

Students and post-docs in the Page lab work on all aspects of materials synthesis, ranging from preparation of bulk solids and gels to thin films, and characterization using XRD, XRR, SEM, EPMA, XPS and ToF-SIMS. In addition, there are multiple opportunities to work with collaborators to learn specialized techniques, such as solid-state NMR, pair-distribution function analysis (PDF), electrical device fabrication, and magnetic measurements. Students will enjoy personalized attention in our small, tight-knit group while also benefitting from the collaborative nature of the larger CSMC community.

Aqueous routes to metal oxide thin films.

The general process employed for aqueous solution deposition involves spin-casting homogeneous solutions of metal salts or clusters onto a flat substrate to form a thin film, then annealing the film to remove water and counterions and to promote cross-linking (condensation) to form a continuous metal oxide network, as illustrated in the cartoon below.

There are several facets to our work in this area:

1) Development of this technique to produce high quality metal oxide thin films at relatively low temperatures for a range of applications, ranging from dielectric gate oxide films to ferroelectric films.

2) Developing a detailed understanding of the chemistry involved in film formation and densification.

3) Developing the use of new and known powerful analytical tools for studying the structural evolution of amorphous films to inform studies of the film formation chemistry.
