About the module

The module combines hands-on operation of high-vacuum instrumentation, high-energy pulsed lasers and surface-characterization techniques. Participants will produce nanoscale crystalline thin films, control deposition conditions and investigate electrode materials for green-hydrogen generation.

Syllabus

  1. Vacuum technology and safe operation of instrumentation.
  2. Materials science and surface-physics fundamentals.
  3. Thin-film fabrication by physical vapour deposition (PVD).
  4. Pulsed lasers and pulsed-laser deposition (PLD).
  5. X-ray reflectivity and diffraction, XPS and electron microscopy.
  6. Laser-induced breakdown spectroscopy.
  7. Hydrogen generation using electrochemical cells.

Prerequisites

No prerequisites.
