Timing and Structure
Michaelmas term. 14 lectures + examples class. Assessment: 100% exam. Lectures will be recorded
The aims of the course are to:
- Understand the basic principles behind quantum mechanics and be able to apply it to problems relevant to Electrical Engineering
- Explore the concepts of quantum information processing and quantum computing
- Become familiar with nanotechnology, what it is, where it is used, and how it relates to quantum systems
As specific objectives, by the end of the course students should be able to:
- Apply quantum principles to understand charge transport and current flow at the nanoscale
- Understand quantum confinement, the origin of band structure, and how it relates to quantum size effects
- Be able to predict basic electrical properties of materials
- Understand and explain the principles behind thermal conductivity of materials
- Describe the operation principle of a quantum computer
- Understand the basic relationships between size and properties of materials, their quantum origin, and their application via nanotechnology
The aim of this module is to introduce (building on material in 3B5) the concepts underlying quantum mechanics and nanotechnology, and see how to apply them to problems relevant to electrical engineering. We will explore the quantum origin of many of the properties of materials, ranging from resistivity, mechanical properties, colour, and band structure, and how these properties evolve with size. We will approach this from two angles: from the theoretical principles and predictions of quantum mechanics, to the manifestations of these as exploited using nanotechnology.
All lectures will be delivered by Dr Sapienza.
- The need for a quantum description of the world around us.
- The basic assumptions of quantum mechanics.
- The Klein-Gordon equation & the Dirac equation.
- Solutions to the Schrodinger equation - confinement, band structures, quantum harmonic oscillator.
- Interpretation of quantum mechanics.
- Everyday examples of quantum mechanics at work.
- A quantum description of electrical properties of materials, and where Ohm's law comes from.
- Mesoscopic transport & the Landauer-Buttiker formalism.
- A look into the principles underlying quantum information processing.
- Entanglement, encryption and quantum computing.
- Nanotechnology - what it is and relationship to quantum mechanics.
- Nanomaterials, evolution of properties of materials with decreasing size, dimensionality.
- Ultimate nanostructures - graphene, molecular systems, novel device architectures.
Change of Rubric: In order to bring the paper structure in line with other IIB modules, the exam format from 2023 will comprise a paper with 4 questions, of which 3 need to be answered, as opposed to previous years where it was 3 out of 5.
Please refer to the Booklist for Part IIB Courses for references to this module, this can be found on the associated Moodle course.
