During Amin Abnavi’s PhD program, he developed innovative optoelectronic devices that use two-dimensional (2D) materials, and have wide-ranging real-world applications in sustainable energy, sensing, and neuromorphic computing. His thesis, , describes his work.  

His research introduced several novel device architectures, such as asymmetric geometries in 2D materials—that not only improved the performance of flexible thin-film solar cells and photosensors but also simplified their fabrication processes. He also developed an optoelectronic logic gate based on 2D materials, capable of performing multiple computing functions in a single device—unlike traditional logic gates that can only do one task. This work paves the way for more compact and powerful computing technologies. His research on suspended 2D material device architectures also led to the development of artificial synapse-like optoelectronic devices that mimic the learning and processing functions of the human brain, enabling high-speed and low-power neuromorphic computing systems.

Abnavi’s research has been published in high-impact journals, with several of his works featured as cover articles in recognition of their significance. During his graduate studies, he received several prestigious awards, including the Canadian Queen Elizabeth II Diamond Jubilee Scholarship, the Kaiser Foundation for Higher Education Graduate Scholarship (twice), and the Lang Wong Memorial Scholarship in Engineering (twice). Abnavi has also acted as a referee for multiple journals and has received the “Outstanding Reviewer of Nanotechnology” award.

Michael Adachi, Abnavi’s doctoral supervisor, is impressed with Abnavi’s work.

Says, Adachi, “[Abnavi] has been an innovator and leader in the research group, discovering new device architectures and proposing them for new applications and developing new device characterization techniques such as photocurrent mapping. His PhD work resulted in 8 first or equal contribution journal articles and an additional article almost ready for journal submission. He was a pleasure to work with and excelled while working in a team.”

Abnavi shares his gratitude for the support he’s received throughout his doctoral studies.

Says Abnavi, “It is a great honor to receive this recognition. I am deeply grateful to my supervisor, Dr. Michael Adachi, whose mentorship, trust, and encouragement shaped the direction of my research. I also extend my gratitude to my colleagues, SFU community, and funding organizations for their support and inspiration throughout my PhD journey. “

Abnavi is continuing his work as a postdoctoral fellow at the University of Victoria, where he is working on developing hybrid systems that can harvest energy from both sunlight and raindrops.
