Program
Day 1
Raman spectroscopy
- Basic principle and advantages of raman spectroscopy
- Instrumentation
Practical session
- Optimization of the parameters: How to choose the laser, the grating, the confocal hole, the laser power
- How to make a Raman image (2D)
- Data evaluation: cursors, CLS fitting, peak fitting
- Fast mapping using SWIFT XS
Objective: Being able to select the good parameters for Raman imaging and to perform data process
Scanning Probe Microscopy (SPM)
- Instrumentation
- The different modes (AFM, STM, Tuning Fork) and signals (Topography, Phase, KPFM, C-AFM, MFM, PFM)
Practical session
- Tips and sample installation
