Nanomachines & Nanomanipulation Structural and chemical analysis of complex layered structures

This project aims at the structural and analytical characterization of novel and complex layered materials, typically MoS2, WS2, NbS2/PbS and their doped variants. The main goal is to reveal these materials’ structure with high spatial resolution and to understand the correlation between their synthesis procedure and the resultant morphology and growth mechanism. Typical microscopy approaches used in such projects are aberration-corrected HRTEM and HRSTEM, high resolution EELS and XEDS spectroscopies, and atomic scale modeling and multislice image calculation. 

The motivation behind the studies in this project is to support the development of novel materials that profit from properties that are enhanced by a 2D-layered morphology. Even though this is a relatively new research area, examples in the literature already report that this class of materials may be used to achieve improved performances on different applications related to microelectronics, catalysis and tribology. This project represents a collaboration with Forschungszentrum Jülich (Germany), Ben-Gurion University of the Negev (Israel), Weizmann Institute of Science (Israel) and LIEC-UFSCar (Brazil)
