*Laboratory of Scanning Electron Microscopy
Doctoral study programme Physics
Objectives and competences
• To make the students introduced to the basics of Scanning Electron microscopy and related techniques (EDX, CL)
• To present some selected case studies
• To get practical hands-on experience and basic authonomy in: preparing sample, setting the intrument, performing the measurement with different signals (secondary, backscattered, EDX), correctly analyze and interpret the collected data and display them into a report.
Prerequisites
/
Content
- Introduction to Scanning Electron Microscopy: motivations, typical investigated systems, apparatus
- Beam-specimen interaction: generation of secondary electrons, backscattered electrons, photons in X-ray and visible range.
- Sample preparation: general guidelines and some laboratory demonstrations
- Operating the microscope: sample mounting, starting the microscope, alignement, criteria for choosing correct measure parameters. Safety rules.
- Surface morphology investigation with secondary electrons
- Surface topography exploiting elemental contrast with backscattered electrons
- Energy dispersive X-Ray spectroscopy (EDX): principles, qualitative and quantitative mapping and spectroscopy.
- Cathodoluminescence spectroscopy (CL): principles and some case studies.
- Data analyis and reporting
Intended learning outcomes
Knowledge and understanding:
• Basic knowledge about Scanning Electron Microscopy and related techniques (EDX, CL) working principles, data analysis, interpretation of results, reporting of results
Practical skills:
• At the end of the course the student is authonomous in planning a measurement session, in preparing a sample and in its morphological and elemental analysis at a basic level
