Summary

This module introduces you to the physical properties of semiconductors and low-dimensional systems, such as quantum wells, wires, and dots. The aim is to explain the physics that underlies optical and transport properties of these structures and their applications in advanced technologies. 

This course is structured in two main parts. The first part focuses on the foundation of quantum mechanics and solid-state physics needed to describe a low dimensional system. The module then moves on describing the physical principles of semiconductor junction and devices. 

List of topics

1.Semiconductors and quantum confined structures: semiconductor materials and band structure; semiconductor heterostructures and band alignment; low dimensional structures: Quantum wells, wires and dots.

2.Semiconductor statistics and doping: density of states in 3D, 2D and 1D structures; Intrinsic and extrinsic semiconductors.

3.Optical and electrical properties: absorption and emission; radiative and non-radiative recombination; carrier drift, diffusion and injection; continuity equation.

4.Semiconductor junctions: p-n junction; metal-semiconductor junction; examples of applications.

5.Tunneling transport: transfer matrix formalism; potential step, single barrier and double barrier.
