Module overview





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.





 

Module aims

To provide students with a basic understanding of discrete electronic and photonic devices and an introduction to the topics of integration and low dimensional devices.  Students will be introduced to the wave nature of light and the underlying physics of semiconductors and carriers in 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 electronics, including both nano-electronics and also large-area printed electronics.

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).


 





 

Assessment Strategy

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)
