ELECTRONICS & PHOTONICS DEVICES - 2021/2
Module code: EEE2042
In light of the Covid-19 pandemic, and in a departure from previous academic years and previously published information, the University has had to change the delivery (and in some cases the content) of its programmes, together with certain University services and facilities for the academic year 2020/21.
These changes include the implementation of a hybrid teaching approach during 2020/21. Detailed information on all changes is available at: https://www.surrey.ac.uk/coronavirus/course-changes. This webpage sets out information relating to general University changes, and will also direct you to consider additional specific information relating to your chosen programme.
Prior to registering online, you must read this general information and all relevant additional programme specific information. By completing online registration, you acknowledge that you have read such content, and accept all such changes.
Expected prior learning: Learning equivalent to Year 1 and Year 2, Semester 1, of EE Programmes.
Module purpose: Using lectures, problems classes, worked examples and tutorial sheets this module will provide the fundamentals needed to understand the operation of key electronic and photonic devices as determined by their fundamental semiconducting properties. The module will also provide a brief introduction to more advanced topics covered in the Year 3 modules.

 Revision. (3hrs)
|Assessment type||Unit of assessment||Weighting|
|Examination||2 HOUR CLOSED BOOK EXAMINATION||100|
Not applicable: students failing a unit of assessment resit the assessment in its original format.
The assessment strategy for this module is designed to provide students with the opportunity to demonstrate the learning outcomes. The written examination will assess the knowledge and assimilation of terminology, concepts and theory of two parts of the module: electronic and photonic
Thus, the summative assessment for this module consists of the following.
· 2 hour closed book written examination
Formative assessment and feedback
For the module, students will receive formative assessment/feedback in the following ways.
· During lectures, by question and answer sessions
· During tutorials/tutorial classes
· By means of unassessed tutorial problem sheets (with answers)
- To provide students with a basic understanding of discrete electronic and photonic devices. Students will be introduced to the wave nature of light and the underlying physics of semiconductors. The structure and operating principles of key electronic and photonic devices will be described. Students will be introduced to the most recent developments in photonic and optoelectronic devices.
|1||Relate experimentally observed phenomena to the properties of semiconductors.|
|2||Explain behaviour of electric current in semiconductors and relevance to electronic devices.|
|3||Discuss the basics of charge carrier properties in semiconductors.|
|4||Compare key semiconductor devices and explain their operation.|
|5||Critically assess the development and progress of semiconductor electronics and the significance of novel semiconductor materials.|
|6||Apply a working knowledge of the wave nature of light and the basic laws of optics to opto-electronic devices.|
C - Cognitive/analytical
K - Subject knowledge
T - Transferable skills
P - Professional/Practical skills
Overall student workload
Independent Study Hours: 70
Lecture Hours: 36
Methods of Teaching / Learning
The learning and teaching strategy is designed to achieve the module aims by exposing students to key areas of modern semiconducting devices, including semiconducting materials, underlying physics phenomena and operation of devices. Students will be shown real samples of semiconductors and a range of electronic and photonic devices to demonstrate the connection between the course material and real life applications. Students will be motivated to learn about new developments in the field including nanotechnology and large area electronics.
Learning and teaching methods include the following:
- Lectures (3hrs x 10 weeks).
- Tutorials (1hrs x 2 weeks).
- In class discussions (as part of lectures x 10 weeks).
- Private study of specified material (texbooks, web, articles) (3hrs x 10 weeks).
Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
