Surfaces and interfaces

MSE-304 / 3 crédits

Enseignant: Stellacci Francesco

Langue: Anglais

Summary

This lecture introduces the basic concepts used to describe the atomic or molecular structure of surfaces and interfaces and the underlying thermodynamic concepts. The influence of interfaces on the properties of materials is also discussed.

Content

- Crystallographic representation of surfaces, reconstruction
- Epitaxial growth
- Surface energy
- Solid-liquid interfaces, interfacial energy, work of adhesion
- Solid-solid interfaces, grain boundaries, interfacial energy
- Surface energy, surface states and catalysis
- Electronic properties of surfaces, work function, surface dipoles
- Surface states
- Effect of surfaces in bulk materials properties.

 

Learning Outcomes

By the end of the course, the student must be able to:

  • Analyze a surface reconstruction
  • Anticipate the stability of a given interface
  • Decide what are the necessary thermodynamics concept to describe an interface
  • Anticipate the behaviour of molecules close to the interface
  • Infer certain processes at the interface

Teaching methods

Ex cathedra (flipped classroom) and exercises

Assessment methods

The course is evaluated by an oral final exam during the exam session.
