State-of-the-art nanotechnology facilitates the creation of electronic devices so small that both the particle and the wave nature of the electrons are important. In such devices quantum mechanics can thus play an important role, which in principle could enable us to realize science-fiction-like quantum technologies such as quantum computation and quantum cryptography.
This course will cover the key concepts of quantum transport in nanoscale electronic devices, from a theoretical perspective. We will start by briefly discussing the basics of solid-state physics that underlie most nanoscale fabrication techniques. Then we will introduce the scattering-matrix description of electronic transport and noise on the nanoscale and use it to derive the simple Landauer-Büttiker formalism. This will allow us to understand several different quantum-mechanical transport phenomena, including the quantum Hall effect, resonant tunneling, persistent currents, weak localization, universal conductance fluctuations, and Coulomb blockade. In the last part of the course we will introduce the fields of spintronics and quantum computation as examples of quantum technologies that are based on the phenomena we discussed earlier.
- A thorough understanding of the basics of electron transport in nanoscale devices.
- A good overview of the most important quantum-mechanical effects in this context.
- Familiarity with several simple theoretical frameworks to describe and understand these effects.
- Basic understanding of the advantages and principles of several proposed quantum technologies, in particular spintronics and quantum information.
- The student will learn how to analyze quantum effects and phenomena in electronic devices, using the simple intuitive formalisms we will derive in the course.
- The student will acquire a good overview of the present status of the field of nanophysics / quantum technologies.
