Surface Analysis
Note from June 29, 2020
Although we do not yet know how long the social distancing related to the Covid-19 pandemic will last, and regardless of the changes that had to be made in the evaluation of the June 2020 session in relation to what is provided for in this learning unit description, new learnig unit evaluation methods may still be adopted by the teachers; details of these methods have been - or will be - communicated to the students by the teachers, as soon as possible.

Specific learning outcomes of the course
a. Disciplinary Learning Outcomes:
Electron and ionic spectroscopies:
At the end of the course, the student will be able to
  • understand and explain the physical (or physico-chemical) mechanisms underlying the considered spectroscopic and spectrometric methods.  These methods include electron spectroscopies (LEED-RHEED, AES, XPS-ESCA) as well as ionic spectroscopies (ISS, RBS) and mass spectrometries (SIMS, LDIMS, MALDI);
  • discuss the specifics of each method, compare the information they allow to obtain and their fields of application;
  • explain the principle scheme of the different instruments and describe their main components (ex. ion gun, electrostatic analyzer, multichannel detector);
  • identify the performance, the limitations (ex. sensitivity, quantification) as well as the possible artifacts related to the different analysis methods, be critical of the data interpretation;
  • provide examples of applications of the analytical techniques in the context of surface treatment and processing (ex. PVD, plasma treatments, thin layer deposition);  
  • select an appropriate method for the structural or chemical analysis of an unknown solid sample;
  • justify the choice of method(s) to answer a problem in materials characterization (such as those encountered in the industrial context).
Scanning probe microscopies (SPM):
At the end of the course, the student will be able to
  • identify and explain the physical, chemical and physico-chemical phenomenons at the basis of the functioning of scanning probe microscopies (STM, AFM, C-AFM, LFM, FMM, AM-AFM, FM-AFM, MFM, EFM, PFM, KPFM, ');
  • describe the instrumentation and explain the functioning of these microscopies;
  • compare them regarding the physical, chemical or physico-chemical properties they allow to measure and map;
  • make and justify the choice of the adequate technique to characterize a specific property of a given material;
  • explain the artifacts that may bias this type of analysis and to criticize results obtained with one of those techniques on this basis.
b. Transversal Learning Outcomes:
At the end of the course, the student will be able to:
  • critically discuss the experimental results with experts in the considered domains;
  • write a concise lab experiment report, structured and adequately illustrated, describing the technical aspects of the experiments, from the sample preparation protocol to the obtained results, in a precise scientific language.
