Science Seminar Series—Structure and properties in hierarchical organic/inorganic materials: Insights from theory

Dr. Paci, graduate advisor in chemistry at the University of Victoria, presents Structure and properties in hierarchical organic/inorganic materials: Insights from theory as part of the Science Seminar Series.

Abstract

In the bottom-up approach to nanotechnology, molecular-scale devices are constructed by designing their components to self-assemble and realize a desired structure or complex.

In this context, the self-assembly process often occurs in the vicinity of a solid substrate.

Theoretical investigations of surface self-assembly and the properties of such materials can be extremely useful counterparts to experimental studies, but can be challenging to pursue.

One main issue is that while ultimately, quantum level information about the molecules, the surface and their interactions is essential to understand, the representative size of the system is more amenable to bulk simulations.

This presentation will describe some of our group’s efforts to advance the theoretical understanding of molecular self-assembly and behaviour on solid surfaces.

Our studies of the formation of organized patterns upon adsorption and their relationship to molecular structure will be discussed in some detail.

During the second part of the talk, we present our investigations of field-response properties of nano-structured material.
