SEMICONDUCTOR DEVICES AND OPTOELECTRONICS - 2024/5

Module Overview

Expected prior learning:  Module EEE2042 – Electronic and Photonic Devices, or equivalent learning, is advisory but not required.

Module purpose:  Semiconductor devices and optoelectronics play a major technology enabling amongst other things the internet. The course is given via a series of lectures and aims to give a background to the interaction of light with key photonic materials and devices. This module will introduce students to modern energy efficient electronic and photonic devices concentrating on the fundamental science of operation, device structure and characteristics.

Assessment Strategy

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

·         The examination measures their level of understanding of the lectured material and their ability to apply it successfully to problems.

The summative assessment for this module consists of:

• a written open book examination.

Formative assessment and feedback

For the module, students will receive formative assessment/feedback in the following ways:

·         Students are provided with exercise sheets and model solutions via the module's SurreyLearn site.

·         Timetabled lecture sessions are devoted to attempting these in a tutorial setting.

          ·        Dedicated question-and-answer sessions occur in other lectures.

 

Module aims

• This module builds upon EEE2042 Electronic and Photonic Devices and EEE2045 Electrical Science II which introduces students to the underlying science of modern electronic and photonic devices (EEE2042) and CMOS based devices and architecture (EEE2045). There are two main aims associated with this module. The first part of the module (Part A) is to understand the challenges faced by industry in developing and providing the next generation of energy efficient and sustainable electronic devices ('More than Moore') which power consumer electronics. The second part of the module (Part B) is to demonstrate how optoelectronics can be used in everyday use, such as the internet and communications.
• The course is given via a series of lectures and aims to give a background to the interaction of light with key photonic materials and devices. The module can lead on to an advanced module on electrical transport in low dimensional systems (EEEM022, Nanoelectronics and Devices).

Learning outcomes

Methods of Teaching / Learning

The learning and teaching strategy is designed to enable students to achieve a working knowledge of state-of-the-art optoelectronic devices and of optical systems for application in industry or research.

Learning and teaching methods include the following.

• Lectures where key concepts will be introduced and students will learn about how fundamental concepts and be the cornerstone of the next generation of energy efficient devices


• Case Study of selected growth of important semiconductor materials


• Problem classes with full sample solutions to allow the students to pace their learning at the pace they are comfortable with.


• Revision sessions of past examination papers; students will be encouraged to attempt the examination papers in advance and to compare their answers with the model solution

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.

Other information

Sustainability: Energy efficiency is at the heart of electronic and optoelectronic devices. In this module students be exposed to the competing user demands of increasing device performance at lower power. This theme runs throughout this module and is aligned to UN SDG no. 7 ("Ensure access to affordable, reliable, sustainable and modern energy for all").

The module provides ample opportunity for students to demonstrate their mastery of advanced calculations, which will aid the student’s employability. The students’ resourcefulness and resilience will be enhanced as they will need to think critically and exercise engineering judgment of some of the underlying assumptions they would need to employ in these calculations.

The student’s digital capabilities will be enhanced via the student’s use of software to solve some of the calculations encountered.
