The course introduces the field of effectively two-dimensional matter with a focus on contemporary research topics in the area of atomically-thin semiconductors. Discussed will be fundamental phenomena associated with interacting electronic quasiparticles in such structures, their coupling to external fields, as well as an overview of the experimental methods for their study. The structure of the course:
Chapter 1: Low dimensional matter
- Quantum mechanical particles,
- Confinement effect
- Concept of 2D matter
- Quantum well structures
Chapter 2: Van der Waals materials
- Coupled potential wells & van der Waals interaciton
- Graphene: structure and electronic properties
- Beyond graphene: 2D insulators, semiconductors & inorganic-organic hybrids
Chapter 3: Two-dimensional materials in experiment
- To find a monolayer: Optical techniques
- To prove a monoalyer: Structural techniques
- To find monolayers fast: Raman and second-harmonic spectroscopy
Chapter 4: Atomically-thin semiconductors
- Indirect to direct bandgap transition
- Coulomb interactions: free and bound charge carriers, excitons
- Heterostructures: indirect excitons & Moiré effects
