Ontario Tech acknowledges the lands and people of the Mississaugas of Scugog Island First Nation.

We are thankful to be welcome on these lands in friendship. The lands we are situated on are covered by the Williams Treaties and are the traditional territory of the Mississaugas, a branch of the greater Anishinaabeg Nation, including Algonquin, Ojibway, Odawa and Pottawatomi. These lands remain home to many Indigenous nations and peoples.

We acknowledge this land out of respect for the Indigenous nations who have cared for Turtle Island, also called North America, from before the arrival of settler peoples until this day. Most importantly, we acknowledge that the history of these lands has been tainted by poor treatment and a lack of friendship with the First Nations who call them home.

This history is something we are all affected by because we are all treaty people in Canada. We all have a shared history to reflect on, and each of us is affected by this history in different ways. Our past defines our present, but if we move forward as friends and allies, then it does not have to define our future.

Title: Multifunctional Materials for Electronics and Photonics

Speaker: Dr. Federico Rosei, Professor and Director, Institut National de la Recherche Scientifique, Énergie, Matériaux et Télécommunications, Université du Québec

Date: September 22, 2 to 3 p.m.

Location: Energy Systems and Nuclear Science Research Centre, Room 1092

Abstract: The bottom-up approach is considered a potential alternative for low-cost manufacturing of nanostructured materials. It is based on the concept of self-assembly of nanostructures on a substrate, and is emerging as an alternative paradigm for traditional top-down fabrication used in the semiconductor industry. We demonstrate various strategies to control nanostructure assembly (both organic and inorganic) at the nanoscale. Depending on the specific material system under investigation, we:

  • Developed various approaches, which include, in particular, control of size and luminescence properties of semiconductor nanostructures, synthesized by reactive laser ablation.
  • Developed new experimental tools and comparison with simulations that are presented to gain atomic scale insight into the surface processes that govern nucleation, growth and assembly.
  • Devised new strategies for synthesizing multifunctional materials for electronics and photovoltaics.
