Mariama Rebello de Sousa Dias, assistant professor of physics, works with Aluminum, Element 13, as part of her research on plasmonics, a field which studies how light interacts with metals at the nanoscale.

Plasmonics has applications in biosensing, energy harvesting, and display technology.

Dias works specifically with an Aluminum-gold alloy that may enhance the performance of nanophotonics devices.

“Pure metallic nanostructures have improved the performance of optoelectronic devices, but there is a limit to the applications,” Dias said. “To overcome this constraint, we propose to use bimetallic structures, like an aluminum-gold alloy, to modulate the optical response of metals. The understanding of how the intrinsic properties of these metallic materials can be manipulated is fundamental to develop the next-generation nanophotonic devices.”

As part of her research with thin film oxides for various applications, Dias has also worked with the following elements: Vanadium, Zinc, Cadmium, Manganese, Yitrium, and Neodymium.
