Fundamentals of semiconductor physics and of light-matter interaction.


A. Heterostructures and 2D systems

Semiconductor heterostructures: growth and fabrication, band alignment. Electronic states and carrier statistics in superlattices and quantum wells. Electron transport in superlattices and multiple quantum wells (intra- and inter-band). Resonant tunneling diodes. Two-dimensional electron gases: modulation doping and electron mobiity, graphene and other 2D materials, graphene stacks. Quantum Hall effects, anomalous Hall effect in graphene.

Optical properties of heterostructures: intraband and interband matrix elements. Quantum-well lasers, quantum-cascade lasers. Photonic crystals, quasi-crystals and random strutures. 2D radiation detectors.

B. 1 and 0 dimensional systems

1D systems: electronic states and statistics, electron transport, conductance quantization, Landauer-Büttiker theory, electronic interferometry. Edge states in quantum Hall effects and their SGM investigation. Many-body effects, charging energy, Coulomb and Pauli blockade in quantum dots.

C. Hybrid nanostructures

Hybrid superconductor-semiconductor systems and their fabrication. Proximity effect and coherent electron dynamics in hybrid nanostructures.

Educational aims

Students will gain a detailed knowledge of the structural, electronic and optical properties of nanostructures. They will be able able to understand the main experimental phenomenologies observed and design novel nanostructures with desired electronic properties.
