Associate Professor, Chemistry; Canada Research Chair in Spectroscopy of Nanoscale Materials

Dr Radovanovic’s research involves studying the optical, magnetic and electronic interactions in nanosystems and their uses in creating next generation forms of information processing and computer memory. The research is relevant in improving computing performance, speed and energy consumption through new forms of non-volatile computer memory that overcome many limits of existing technology.

As Canada Research Chair in Physical Chemestry and Spectroscopy of Nanoscale Materials, Dr Pavle Radovanovic studies how light, magnetic field and electrical current interact in nanometre-scale materials in advanced and next-generation microcomputing. The knowledge gained from this research is a key to designing new forms of information processors and non-volatile Random Access Memory (RAM)—memory that doesn’t disappear with electricity.

One promising new form of RAM stores information with a combination of magnetic field and electricity (magneto-resistance),using much less electrical power in the process. Radovanovic will design nanocrystalline materials that combine the necessary optical, electrical and magnetic properties. By designing and studying these systems, he’ll develop a fundamental understanding of the relationship between the electronic and crystal structure of low-dimensional multifunctional systems and their functional physical properties. His research program will also address the structure-function relationship as a fundamental question in physical-inorganic and materials chemistry. With the RAM and data storage market worth over $100 billion per year, Radovanovic’s research will help ensure Canada is a major player in this field, while advancing the speed and performance of computing, benefiting countless other industries in our increasingly digitized world.

Our research program is concerned with synthesis, fundamental physical and chemical properties, and application of designed nanostructured materials that combine tunable optical electrical and magnetic properties.

We apply a variety of synthetic, crystallographic, microscopic, spectroscopic, magnetic and transport techniques, and perform the measurements of novel nanomaterials at both ensemble and single nanostructure level.

Our approach is to achieve multifunctionality by using complex nanocyrstalline alloys and compounds that contain multiple selected transition-metal or rare-earth-metal sites. Diluted magnetic semiconductors have already found applications in spin-based electronics (spintronics). This alternative technology relies on the use of electron spins, in addition to charges, for efficient and non-volatile information transmission and possessing.

The rational design and study of complex nanocrystalline alloys and compounds can provide important understanding of the relationship between the crystal and electronic structures of low-dimensional multifunctional systems and their optical, electrical magnetic properties. We devote particular attention to the mutual interactions between light, electrical conductivity and magnetization at the nanoscale in the context of novel technological applications. Our long-term goal is to understand these materials at the molecular level and to design improved multifunctional nanostructures based on our knowledge of the structure-function relationship.

Hybrid nanostructures can utilize a variety of properties unique to organic and biological molecules to introduce complex functionalities into inorganic nanostructure. Due to their small sizes, high surface areas and tunable molecule-like electronics structures and physical properties, inorganic nanoscale materials potentially allows for increased compatibility with organic and biological systems over bulk materials.

We are studying electronic coupling between the semiconductor nanostructures and rationally selected organic and biolmolecular adosrbates, which is relevant for nanophotonics and energy conversion technologies. Our goal is to understand the properties of nanocyrstalline-surface-bound molecules and their relationship to the electronic coupling processes.
