Missions

Metal-dielectric nanogap antennas achieve extreme confinement of the electromagnetic field, allowing increased light-matter interaction and thus enhancing a wide variety of physical effects. Their optical modes are characterized by a highly confined field disturbed by the tunnel transport of electrons through the dielectric gap. The combination of these two effects introduces new optical properties, the topic of this research project.
Beyond studying these fundamental aspects, the project will focus on taking advantage of the strong interaction between electronic transport and optical properties to initiate new light sources and new concepts of photo-detection.
This project will be conducted at C2N in the Nano-Opto-Electronic team under the responsibility of Jean-Luc Pelouard.

Activities

The activities of this research project fall into three categories.
1 / Theory and numerical simulation. Many theoretical points remain open in the field of nanogap resonators. This research project aims to make a contribution by developing new models supported by numerical simulations. This activity will be developed in collaboration with two other teams from the Paris-Saclay campus.
2 / Nano-manufacturing. This part is based on the experience of our team for the fabrication of nanogap devices, mainly the control of thicknesses and interfaces on a scale clearly below the nanometer. In this context, this project aims to develop new approaches allowing, in particular, an increase in the applied voltages, a reduction in noise and a better stability over time of the electrical characteristics. This activity will take place in the C2N clean rooms.
3 / Characterization of the optical and electrical properties. The fabricated structures will be characterized on the laboratory test benches for their optical and electrical properties. Beyond these standard characterizations, specific setups will be used for more detailed studies. They will be carried out, either through collaborations, or by carrying out dedicated setup in our laboratory.

Skills

The activities planned in this project cover a vast field ranging from theoretical studies to experimental characterizations, and to nano-fabrication in a clean room. We are looking for a person who already has experience in at least two of these three areas, including nano-manufacturing.
This research subject is at the forefront of knowledge both from an electromagnetic point of view, as well as electronic transport or the physico-chemistry of materials and their interfaces. The candidate's scientific and technical background and experience should cover a large part of this field. This aspect will be an important criterion in the selection of candidates.

Work Context

The Center for Nanoscience and Nanotechnology (C2N) is a joint research unit of the CNRS and the University of Paris-Saclay. Made up of approximately 410 people, the laboratory integrated its brand new building on the Paris-Saclay campus in the fall of 2018. C2N's research themes are photonics, nanoelectronics, microsystems and nano-bio-fluidics and materials. The position to be filled is within the Nano-Opto-Electronic (NOE) team in the photonics department.
The candidate will benefit from the support of the laboratory's PIMENT and PANAM platforms for the fabrication and structural characterization of the studied structures. More details on our web site: www.c2n.universite-paris-saclay.fr/en
The research project will take place within the framework of close collaborations with other teams at the Plateau de Sacaly (IOGS, CEA, ISMO, III-V Lab) for both theoretical and experimental approaches, in particular those within the metanizo program of the ANR.

Constraints and risks

The research project will be carried out at C2N. Part of it is to be expected to be done in other laboratories on the Paris-Saclay campus (see collaborations above) for meetings and / or joint work.
