In this talk I will review the effect of quantum confinement on the electronic and vibrational properties of one-dimensional carbon nanoribbons. The talk will present research conducted at the interface between theory and experiment where a combination of disciplines is found to lead to an atomistic understanding of measurable properties of low-dimensional structures.[1-3] Inspired by the recently developed capability of assembling nanostructures from the bottom up with atomic precision, the field devoted to the detailed understanding of the physics of carbon nanostructures is poised to offer an unprecedented test-bed for predictions of quantum confinement. In particular, the emergence of magnetic states, tunable electronic properties, vibrational (and thermal) properties is now being exploited as a real possibility to develop carbon-based devices of the future, with higher density of information and processing power. I will use specific examples to illustrate that as we venture into a new regime of material science research where the position of each atom is known precisely, theoretical description is found to face new challenges that are not apparent in defective materials.

Vincent Meunier is head of the Physics, Applied Physics, and Astronomy Department at Rensselaer Polytechnic Institute where he holds the Gail and Jeffrey L. Kodosky ’70 Constellation Chair. Meunier earned his PhD from the University of Namur in Belgium in 1999 under the supervision of Professor Philippe Lambin. He was a Senior R&D staff member at Oak Ridge National Laboratory until 2010 when he joined Rensselaer. He has published approximately 210 papers in peer-reviewed journals and is a Fellow of the American Physical Society. Meunier leads the Innovative Computational Material Physics (ICMP) group at Rensselaer. His research uses computation to examine the atom-level details of materials. He is particularly interested in low-dimensional materials and domains where he can collaboratively work with engineers and experimentalists to optimize these materials, starting at the atomic level and targeting functionality.
