Prerequisites / Co-requisites
This module will review crystal structures, will develop the concepts of heat transport and heat capacity in crystalline solids and introduce the concept of quantisation of lattice vibrations (phonons). The module will introduce the free electron theory of metals and introduce band theory. The concept of semiconductors will be discussed and the physics of modern photonic devices such as semiconductor lasers, photo-sensors and nuclear radiation detectors will be introduced.
develop key concepts in solid-state physics including crystal structure and dynamics, concept of densities of states, lattice and electronic heat capacity and the band theory of solids. The difference between metals, insulators and semiconductors will be discussed and the module will show how semiconductors play a pivotal role in modern electronic and photonic devices.
Laboratory classes will be used to reinforce concepts developed in the lectures and will be used to further develop and enhance laboratory skills, particularly in the area of analysis and spectroscopy.

Indicative content includes:
The lecture course will cover the following topics:
Crystal structure: Revision of crystal structures, the reciprocal lattice and a review of X-ray diffraction technique.
Lattice dynamics: Lattice vibration, concept of phonons and phonon modes, density of states, derivation of Dulong-Petit, Einstein and Debye models of heat capacity, electronic heat capacity and electrical conductivity.
Band theory: Free electron model, energy-momentum dispersion relationship, concept of Brillouin zones, band structure and band gaps, distinction between metals, insulators and semiconductors.
Semiconductor device physics: Doping of semiconductors, pn junction diodes, basic introduction to emission and absorption in semiconductors photonic and sensor devices (light emitting diodes, semiconductor lasers, photodetectors and nuclear radiation detectors).
The laboratory experiments will include: X-ray diffraction, photoluminescence spectroscopy, absorption in semiconductors,characterisation of semiconductor lasers and LEDs.
Methods of Teaching / Learning
The learning and teaching strategy is designed to:
• equip students with subject knowledge
• develop skills in applying subject knowledge to physical situations
• enable students to tackle unseen problems in solid state physics
• advance students' practical skills
The learning and teaching methods include:
• 33h of lectures and tutorials as 3h/week over 11 weeks
• 1-week experiments throughout semester (22 hours laboratory work)
The assessment strategy is designed to provide students with the opportunity to demonstrate
recall of subject knowledge
ability to apply subject knowledge to unseen problems
practical laboratory skills
scientific communication skills
Thus, the summative assessment for this module consists of:
An end of semester examination of 1.5 h duration with 2 questions from 3 to be attempted
The laboratory coursework is assessed through a combination of interviews, written reports and a poster presentation.
Problem sets are provided during the weekly 1 hour tutorial on solid state physics, together with model answers to these questions, which allow the students to test their understanding of course material. Formative assessment during the laboratory classes is provided by an online quiz for each experiment carried out each week by the students to prepare for the forthcoming laboratory experiment.
Verbal feedback is provided during the weekly 1 hour tutorial throughout the semester. Model solutions are provided for the questions on the problem sets to provide students with feedback on their problem-solving ability. Feedback during the laboratory classes is provided by demonstrators and staff giving verbal feedback and support during the class.
