Noble-metal nanoparticles (NPs) and clusters are being used for a large number of applications, ranging from plasmonics to bio-labeling and -sensing, catalysis, surface-enhanced Raman spectroscopy (SERS) and a multitude of other applications. Most exploitable properties depend sensitively on NP size, structure, composition, and, in particular, the environment. However, the fundamental physical understanding of intermediate-sized clusters (around 2nm) and their optical properties is still rather poor, experimental benchmark results are only beginning to be available. Recent cutting-edge experiments highlight the importance of the environment.

The fascinating PhD project combines the use of quantum theory with the study of real materials that are both scientifically and technologically relevant. In the proposed thesis work, we will study the influence of the environment and, in particular, of the nature and the arrangement of ligand molecules on the optical properties of monolayer-protected clusters, mostly of gold. This field is extremely active, at the moment, with many groups studying these systems. The study will be carried out primarily based on Time-Dependent Density-Functional Theory (TDDFT) in atomistic calculations.

The full description of the project with literature references and contact details can be found here: https://amubox.univ-amu.fr/s/2MnwB2rAiNPXDMX

The work will be carried out at the CINaM, Marseille, and within a network of national (Lyon, Orsay) and international (Spain, USA) collaborations, both theoretical and experimental.

Candidates should have a solid background in condensed matter physics and/or quantum chemistry, with working knowledge on computational and numerical methods. Research experience at MSc level is required, preferably in the development and/or application of ab initio modeling tools. Furthermore, the candidate should be enthusiastic about the prediction and theoretical understanding of quantum phenomena concerning light-matter interaction at the nanoscale. He/she must be interested and able to work within international teams.

Candidates are invited to contact H.-Ch. Weissker no later than Monday, May 18, 2020. In the application procedure, the profile/quality of the candidate (grades!) has a large weight. Necessary documents for the application are: a CV with the grades of previous education (in particular during MSc) and two letters of recommendation, as well as a letter of motivation (French or English).
