Fundamentals of band theory and of light-matter interactions.

Syllabus

A. Heterostructures

Semiconductor heterostructures: growth and fabrication, band alignment. Electronic states and carrier statistics in superlattices, quantum wells, quantum wires, and quantum dots. Electron transport in superlattices, resonant tunneling diodes and transistors.

Two-dimensional electron gas. Modulation doping. Graphene and other 2D materials. Optical properties: intraband and interband matrix elements. Quantum well lasers, quantum cascade lasers. 2D photodetectors.

B. 1 and 0 dimensional systems

1D systems: electron transport, conductance quantization, Landauer-Büttiker theory, electronic interferometry. Quantum Hall effects and edge states. Anomalous Hall effect in graphene. Many body effects, charging energy, Coulomb and Pauli blockade in single and coupled quantum dots.

 

Educational goals:

The students who will successfully complete the course 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 in nanostructures.
