Abstract: Understanding and controlling the properties of 2D materials to our advantage can be contemplated with the development of experimental tools to probe and manipulate electrons and their interactions at the atomic scale. In this talk, I will present scanning tunnelling microscopy and spectroscopy experiments aimed at: elucidating the nature of atomic-scale defects in 2D materials [1], visualizing moiré patterns between crystals with different symmetries [2] and imaging surface and edge states in a magnetic topological system. Moreover, I will discuss how we leverage our expertise in probing and engineering electronic states at surfaces of 2D materials to further the development of graphene-based gas sensors [3] and gated quantum dot circuits based on 2D semiconductors [4].

Bio: Adina Luican-Mayer is an assistant professor in the Physics Department at uOttawa since January 2016. She received her undergraduate degree from Jacobs University Bremen in Germany (2006) and her PhD in Physics from Rutgers University (2012) in the US. Prior to joining uOttawa, she was the Alexei Abrikosov postdoctoral fellow at the Center for Nanoscale Materials at Argonne National Laboratory. Her research group focuses on uncovering the novel electronic properties of low-dimensional quantum systems using scanning probe microscopy and supporting spectroscopic techniques.
