ECE Colloquium Series – Professor Luis Martin-Moreno
April 20 @ 3:30 pm - 5:00 pm
As part of the *Eleanore Hale Wilson Lecture Series, ECE is proud to present:
Plasmons in 2D materials: Scattering and magneto-optical phenomena
Professor Luis Martin-Moreno
University of Zaragoza
Hosts: Professor Sang-Hyun Oh and Professor Tony Low
After his discovery a decade ago, Graphene (a one-atom thick material compose of carbon) has made the headlines due to its amazing electronic and elastic properties. However, its electromagnetic properties are no less remarkable. Partly this is because doped graphene is able to bound electromagnetic waves (known as Graphene Plasmons) very tightly and, moreover, in a way that depends on the doping, which in turn can be control externally with a bias. In this graphene is not alone: its discovery has unveiled a whole family of 2D materials, which also support plasmons with different characteristics. In this talk I will present the basis of light-matter interaction in atomically-thick materials, and concentrate on two basic problems: the scattering of plasmons by either geometrical of conductivity defects (which is a first step towards the control of these waves) and the possible use of graphene plasmons in the rotation of polarization of light (Faraday effect), which may have applications in devices in the THz regime.
I did my Doctorate in Physics in 1989 at Universidad Autonoma de Madrid (Spain) on the topic “Electronic structure of amorphous semiconductors based on Silicon.” Then I did a 3 year post-doctoral stay in the ’Semiconductor Physics group” of the Universidad de Cambridge (United Kingdom), working on the topic of electronic transport in two-dimensional electron gases, under the supervision of Prof. Michael Pepper. From 1993 till November 1995 I did a post-doctoral stay at the Instituto de Ciencia de Materiales de Madrid, working on magneto-transport in mesoscopic systems. During this time I spent 3 summers at the Imperial College (London, UK), working on the optical properties of nanostructured metals (what has been later termed as “plasmonics”) under the supervision of Prof. John Pendry. In November 1995 I got a position as a lecturer at the University of Zaragoza (Spain) and, since 2008 I am a Professor at the Instituto de Ciencia de Materiales de Aragon (Zaragoza, Spain). In the last ten years, I have been working on nanophotonics, optical and acoustic metamaterials, non-linear effects, the electromagnetic properties of graphene and other atomic-thin materials and in waveguide quantum electrodynamics.
