Assessment pattern

Alternative Assessment

Not applicable: students failing a unit of assessment resit the assessment in its original format.

Assessment Strategy

The assessment strategy for this module is designed to provide students with the opportunity to demonstrate the learning outcomes. The 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.

•          Coursework (20%)


•          Online (Open Book) Exam within 4 hrs Window (80%)

Module aims

• To provide students with a basic understanding of discrete electronic and photonic devices. Students will be introduced to the underlying physics of semiconductors and the wave nature of light. 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.

Learning outcomes

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  (2 hrs x 11 weeks).


• Tutorials (1 hr x 11 weeks).


• In class discussions (as part of lectures  x 11 weeks).


• Captured contents (3 hrs x 11 weeks)


• Private study of specified material (texbooks, web, articles) (84 hours).

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.
