2D-materials in Grenoble: one PhD and two MSc
Two-dimensional materials are of highly significant interest for many applications in nano-opto- electronics. Graphene is the prototype of this material family however the absence of gap limit its potential applications e.g. for making transistors logic field effect. Recently transition metal dichalcogenides (TMDC) have emerged in the growing field of 2D materials and give rise to an new area of research. The proposed research effort is a part of the LANEF "Chaire of Excellence" of Pr. Dimoulas  hosted for three years in Grenoble in a jointed task force between CNRS and CEA (2D@Grenoble). The proposed studies are part of a basic research effort with a medium-term goal (2D Factory) for the design of alternative device based 2D-materials.
Three positions are available:
A PhD grant for MBE/CVD growth of optimized TMDCs and in situ synchrotron x-ray scattering investigations of their structural properties at the European Synchrotron Radiation Facility (ESRF). The outcome of the project will be the determination of one or several techniques to elaborate TMDCs of the highest structural quality, which will promote both fundamental physics of these objects and development of applied devices using them. State of the art synchrotron measurements, performed in situ, during the growth, will provide a detailed understanding of the structural properties, which is a prerequisite to further understand the physical properties or transfer the knowledge to applied devices.
One Master position for the structural study using transmission electron microscopy techniques. Atomic resolution structural analysis will be done in order to understand the fundamental of TMDC structures including the defects and phase transitions which determine their physical properties. Analytical methods required to study atomic structure of TMDC monolayers will be also developed using state of the arts microscopes. This work can be followed by a PhD program on in-situ observation of defect formation and phase transition to study dynamics in TMDC structures and to exploit further potential of these 2D materials for future applications.
One Master position for the theoretical study of TMDC. It includes the use of Density Functional Theory (DFT) in order to assess stable phases and related defects that might drive the corresponding phase transition dynamics. The simulation of such defects requires large models that will be handle using the BigDFT package on massively parallel supercomputers. In a following PhD program, kinetics will be considered using both Monte Carlo simulations and ab-intio based Potential Energy Surface methodologies. The guideline of our approach and further references can be found here .
All positions are available in March 2016. The two Master thesis could be pursued by a PhD starting in fall 2016. The PhD position could start by a Master thesis in Spring 2016, followed by a PhD. Successful candidates should have a strong background in general Physics, and more specifically in Solid State Physics; Material Science; Nanosciences, They should be particularly interested by team work. Application for each position including Curriculum Vitae, cover letter and references, should be send to each contact person before the 4th of December.
