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
  • Molecular resolution in AFM tapping mode
  • Measurements in AC mode, contact mode, I-top mode,
    KPFM
  • Presentation of the dedicated tips and additional
    equipment

Objective: Being able to use the main AFM modes and optimize the parameters


Day 2

Tip Enhanced Raman Spectroscopy

  • Principle and requirements
  • Presentation of the different TERS tips (STM-TERS Au,
    AFM-TERS Au and AFM-TERS Ag)
  • Excitation laser alignment on the TERS tip (rough and
    fine alignment)
  • TERS demonstration on carbon nanotubes and
    graphene oxide flakes
  • Optimization of the TERS parameters (spectra and
    imaging)

Practical session

  • Hands-on on demo samples (AFM mode)
  •  Laser alignment on the tip
  • TERS spectra and TERS imaging on known sample

Day 3

TERS Hands-on
