Contexte

 

As a key player in research and innovation in Luxembourg, the Luxembourg Institute of Science and Technology (LIST), with its employees, is active in the domains of materials, the environment and IT. As an RTO (Research and Technology Organisation) and with its interdisciplinary impact-driven approach, LIST contributes to the development of Luxembourg’s economy and society. The Materials Research and Technology Department (MRT) translates cutting-edge materials research into applicable technology, with about 190 collaborators. For this, the department cultivates close relationships and joint projects with both academic and industrial partners, and contributes to Luxembourg's and Europe's innovation agenda in Materials Research and Technology.

The Advanced Instrumentation for Ion Nano-Analytics (AINA) group within the Scientific Instrumentation and Process Technology (SIPT) unit of MRT is renowned for developing innovative nano-analytical techniques for materials characterisation and life science applications. During the past few years we have been developing in particular a Secondary Ion Mass Spectrometry (SIMS) add-on system for the Helium Ion Microscope (HIM) and for a Transmission Electron Microscope (TEM), allowing the advantages of high spatial resolution with high sensitivity chemical information to be combined for nano-analytics.

 

Description

 

We are looking for a master student to investigate the modification and sputtering of nano-sized objects under ion-beam irradiation. Nowadays, ion beams play an important role for the development and characterisation of nanomaterials. For the characterisation of the latter by secondary ion mass spectrometry and electron microscopy, it is essential to understand how the shape and surface curvature of small objects change during ion irradiation and how the analysis results might be influenced by a substrate in order to convert the recorded signals correctly into a 3D shape and into concentrations.

During the internship, the master student will have the opportunity to become familiar with molecular dynamics (MD) simulations and to study the evolution of the shape and composition of nano-objects under the bombardment with energetic helium and neon ions. The main objective of the internship is to understand how the substrate influences the evolution of shape and composition of nano-objects. For specific configurations, a comparison with experimental data will be possible.
