Probing low-dimensional materials and quantum phenomena with scanning tunnelling microscopy
- Schedule: 03-04/2027
- Hours: 20
- Lecturer: Luca CAMILLI (Tor Vergata)
- Programme: Introduction to the theory of scanning tunnelling microscopy; instrumentation; review of recent literature works on scanning tunnelling microscopy investigation of low-dimensional systems with focus on defect engineering, probing of topological quantum matter and correlated systems; gate-tuneable scanning tunnelling microscopy experiments
- Verification: presentation of a literature study. A list of possible studies that can be presented will be provided, but students are welcome to choose studies other than those suggested.
Theory, characterization and applications of the glassy state
- Schedule: 02-05/2027
- Hours: 20
- Lecturer: Valerio DI LISIO
- Programme: The course aims to provide doctoral students a comprehensive introduction to amorphous solids, combining theoretical background with characterization techniques and presenting notable examples of glasses with advanced applications. The program begins by exploring the non-equilibrium thermodynamics and dynamics of glasses, including the vitrification of supercooled liquids, the glass to liquid transition, the concept of cooperativity and cooperative rearranging regions (CRR), the Angell fragility of liquids, the glass relaxation mechanisms (physical aging), the Kauzmann paradox, the Moynihan “fictive” temperature as glass order parameter. A broad spectrum of glass-forming systems will be examined, including polymers, molecular and inorganic glasses, metallic glasses, together with common methodologies to obtain them, including meltquenching, vapor deposition, solvent casting. The course will then review the key experimental techniques used to probe disordered systems, including thermal analysis, broadband dielectric spectroscopy, dynamo mechanical analysis, diractometric and vibrational techniques. A small module of the course will be dedicated to the "confinement eect," analysing how glass thermodynamics and dynamics are altered when materials are restricted to nanometric domains, such in nanofilms and nanoparticles. Finally, the course will examine some cutting-edge applications of glassy materials in fields such as photonics, pharmaceutics, and organic electronics (OLEDs).
