Offer Description

The successful candidate will investigate, through the effectual combination of
ab initio approaches, semi-empirical methods, and computer simulations, the potentialities of 2H- Si 1-x Ge x NWs as light emitters. The main goal is to reach a deep theoretical understanding, via precise state-of-the-art quantum-mechanical modelling, of the dielectric response of 2H-Si 1-x Ge x NWs in a realistic environment, including morphology, substrates, and dopants. Furthermore, the
activity will provide an accurate interpretation of targeted experiments using advanced nanometre-scale optical measurements with fast electrons that will be conducted in the group.

The main objective of this activity is to investigate, through the effectual combination of ab initio approaches, semi-empirical methods, and computer simulations, the great potential as light emitters of 2H-Si1-xGex NWs in close integration with targeted advanced nanometer-scale optical measurements. The proposal presents two key challenging objectives: (i) the deep theoretical understanding, via precise quantum-mechanical modelling beyond the state-of-the-art, of the dielectric response of 2H-Si1-xGex NWs in a realistic environment, including morphology, substrates, and dopants and (ii) the design and accurate interpretation of targeted experiments using advanced nanometer-scale optical measurements with STEM-EELS. This funding will place the principal investigator in a unique scientific context to create an independent research line in the field of multiscale modelling of nanostructures in close connection with advanced experiments.

The selected candidate will work within the “STEM” team of the Solid State Physics Laboratory (UMR 8502) on the Orsay campus of Paris Saclay University. The Solid State Physics Laboratory is a joint research unit (UMR 8502) of the University of Paris-Saclay and the CNRS. It is affiliated with the CNRS Institute of Physics and the 28th section of the National Council of Universities. The LPS is a member of the Friedel-Jacquinot Federation, the physics coordination structure on the Moulon plateau in Orsay (IdF). It brings together around a hundred researchers and teacher-researchers, experimentalists, and theorists, and the research activity is supported by around sixty engineers, technicians, and administrative staff. The laboratory welcomes a large number of undergraduate and graduate students each year, including many doctoral students, as well as postdoctoral researchers and visiting scientists. The lab covers a wider variety of topics than its name suggests, and aims to address the full diversity of condensed matter physics. Research activity is organized around three main axes, each of which involves approximately the same number of scientists: • New electronic states of matter • Physical phenomena with reduced dimensions • Soft matter and physics-biology interface In the first axis are brought together both experimental and theoretical studies relating to the properties of systems in which electronic correlations are generally strong and which are the seats of remarkable properties and unconventional electronic states such as superconductivity, magnetism, metal-insulator transitions etc. In the second are activities relating to “nanosciences” in the broad sense. They are approached here from the point of view of fundamental properties, when the dimensions of an object become as small as certain characteristic distances (coherence length, mean free path, etc.). The third axis extends the concept of “soft matter” to biological systems. The themes therefore range from complex systems to living tissues, from liquid crystals to foams, including polymers or granular systems. These physical studies are at the interface with physico-chemistry and biology.
