Unit description Unit description

This unit introduces basic thermodynamic principles and connects them with the physical laws and the statistical nature of the microscopic world governing the behaviour of the matter around us. We start out with the concept of temperature and investigate the emergence of the Boltzmann factor in the canonical ensemble. We then proceed with the kinetic theory of gases and discuss transport properties and thermal diffusion. The first and second law of thermodynamics form the foundation for understanding the basic working principles of thermodynamic engines. We next introduce three key pillars of statistical physics: the equipartition theorem, partition functions and the influence of distinguishability on the counting statistics of particles. This sets us up for a discussion of basic solid-state phenomena as they were known in early 20th century, including Debye theory of the heat capacity of solids, the basics of Drude transport theory and Sommerfeld’s electron model.

In order to understand more intricate properties of solid crystals, the periodic nature of the underlying crystal lattice must be considered. The unit will first introduce the 1D solid as a model system for illustrating the basic consequence of having a periodic lattice. The powerful concept of reciprocal lattice is introduced and subsequently generalized to all three dimensions, with specific examples given for the different cubic lattice structures. Wave scattering by crystals and its connection to the reciprocal lattice is discussed with particular view to the X-ray experiment on offer in the labs. Electronic properties are mapped to the existence of band structure and the emergence of band-filling patterns in different materials. Finally, the unit concludes with a discussion of a couple of cutting-edge research topics in modern solid-state physics.

Learning Outcomes

On successful completion of this unit, you will be able to:

  • ULO1: demonstrate an understanding of fundamental thermodynamic principles and their connection to the microscopic dynamics of matter, particularly for gases and crystalline solids.
  • ULO2: describe how the periodicity of a crystal affects measurable quantities such as heat capacity or conductivity, demonstrating insight into the concept of crystal momentum and its implications for band structures and scattering experiments.
  • ULO3: use mathematical descriptions based in real- and momentum-space to solve problems in scattering theory.
  • ULO4: discuss the connection between electronic band structure and certain material properties, with specific examples of low-dimensional electronic systems.
  • ULO5: carry out advanced labs, analysing, interpreting and reporting results in accordance with professional standards.

General Assessment Information

Planning your time

The 'estimated time on task' for each assessment item is an estimate of the additional time needed to complete each assessment outside of all scheduled learning activities. These estimates assume that you actively engage with all scheduled learning activities and spend an additional 31 hours of self-led study during the session. 

If you receive special consideration for the final exam, a supplementary exam will be scheduled after the end of the normal exam period. By making a special consideration application for the final exam you are declaring yourself available for a resit during the supplementary examination period and will not be eligible for a second special consideration approval based on pre-existing commitments. Please ensure you are familiar with the policy prior to submitting an application. Approved applicants will receive an individual notification one week prior to the exam with the exact date and time of their supplementary examination.

Requirements to Pass the Unit

There are no hurdle tasks specified in this unit. Consequently, the requirement to pass is to obtain an overall mark of at least 50% across the three assessment components.

Late Assessment Submission Penalty

Unless a Special Consideration request has been submitted and approved, a 5% penalty (of the total possible mark of the task) will be applied for each day a written assignment or laboratory report is not submitted, up until the 7th day (including weekends and holidays). After the 7th day, a grade of 0 will be awarded even if the assessment is submitted. The submission time for all uploaded assessments is 11:55 pm. A 1-hour grace period will be provided to students who experience a technical concern.

For any late submission of time-sensitive tasks, such as scheduled tests/exams, performance assessments/presentations, and/or scheduled practical assessments/labs, please apply for Special Consideration.

 

Specific assessment information regarding lab experiments and reports

Students will have to conduct four out of the six following experiments available in the practical part of PHYS3180:

  • Debye Temperature
  • X-ray Diffraction
  • Properties of Semiconductors
  • Nuclear Magnetic Resonance
  • Superconductors
  • Fabrication and Imaging of 2D materials 

Please note the following points

  1. You are required to complete four of the experiments.
  2. Students should make a booking for two lab sessions for each experiment they undertake. A booking gives priority provided the students arrive punctually at the start of the laboratory session.
  3. A set of resources folder is available for each project which can be downloaded from iLearn.
  4. You should refer to the document Recommendations for Laboratory Report Writing when preparing reports.  Please ensure that your reports conform to these guidelines, and feel free to discuss this with any of the staff. You are required to write reports for two of the four experiments, one for experiment 1 or 2, and one for experiment 3 or 4.
  5. Reports should not contain text that has been copied from the instructional notes.  You should provide background and discussion material in your own words. It is expected that you produce your own original figures wherever possible, either hand-drawn or computer generated.  Anything taken from another source must be clearly acknowledged.
  6. Besides two formal reports, you are required to write extensive (Python-based)  electronic lab notes that provide the base for the lab report writing. After each 2-week experimental session, the electronic lab notes will be pulled and assessed (worth half of the total lab mark, that is 15% in total). The lab notes should reflect the in-class prac work.
