Abstract
Graphene Nanoarchitectonics: from LEGO Chemistry to Device Integration
Nanostructuring graphene confers multiple functionalities to this material, making it attractive to very diverse applications in (opto)electronics, molecular sensing and filtering. However, many relevant applications require atomic resolution in the structural control, which can only be addressed with bottom-up synthetic approaches.
By following a transformative LEGO chemistry approach known as on-surface synthesis, we have fabricated atomically precise, semiconducting nanoporous graphene architectures [1], tune their anisotropic properties by molecular coupling bridges [2], and built 1 nm wide lateral heterostructure superlattices [3]. Here I will present results on the synthesis and characterization of these nanoarchitectures, as well as our progress in their integration in field-effect transistor-based devices.

Biography
Aitor Mugarza is ICREA Research Professor and Group Leader of the Atomic Manipulation and Spectroscopy Group at ICN2 since 2013. He has been Marie Curie Fellow at the Lawrence Berkeley National Laboratory, USA, and Ramon y Cajal Fellow at ICN2. He is author of 90+ articles, and of 70+ invited talks at international conferences, universities and schools. He is founder and coordinator of the SPM Platform that is being created at ALBA synchrotron. His research activity is based on the investigation of quantum properties of matter on the nanoscale, and developing strategies to manipulate them with atomic precision.
