Module summary
This module provides both fundamental theory and hands-on experience on semiconductor physics, devices, fabrication and analysis techniques. The module will cover first the basic semiconductor physics such as crystal structures, doping and band gaps etc, devices such as diodes and transistors and then various measurement techniques to probe the morphology, compositions, electrical, magnetic and optical properties of materials and devices at nano/atomic scales, along with both conventional nanofabrication techniques (e.g, e-beam lithography) and non-conventional nanofabrication techniques (e.g, self-assembly). The module will provide practical experiences.

Module feedback
'Feedback’ at a university level can be understood as any part of the learning process which is designed to guide your progress through your degree programme. We aim to help you reflect on your own learning and help you feel more clear about your progress through clarifying what is expected of you in both formative and summative assessments. A comprehensive guide to feedback and to forms of feedback is available in the Guide to Assessment Standards, Marking and Feedback.
The School of PET aims to provide some form of feedback on all formative and summative assessments that are carried out during the degree programme. In general, feedback on any written work/assignments undertaken will be sufficient so as to indicate the nature of the changes needed in order to improve the work. The School will endeavour to return all exam feedback within the timescale set out in the University's Policy on Assessment Feedback Turnaround Time. The School would normally expect to adhere to the times given, however, it is possible that exceptional circumstances may delay feedback. The School will endeavour to keep such delays to a minimum. Please note that any marks released are subject to ratification by the Board of Examiners and Senate. Meetings at the start/end of each term provide you with an opportunity to discuss and reflect with your supervisor on your overall performance to date.
Statement of Feedback
Formative Feedback
Regular lab sessions will provide the opportunity to ask questions and receive verbal help and feedback about your progress in developing practical skills.
You will have the chance to discuss and receive feedback on your module work plan and reflective report from your supervisor.
Practice exercises for the continuous assessments will be provided, allowing you to check your progress throughout the module.
Questions can be asked at any time, and will be answered as soon as possible.
Summative Feedback
Individual feedback will be provided on your individual report along with detailed marks and the correct answers.
Indicative reading
If you would like to purchase a textbook which will cover most of the material you will study during this module, this would be a good book to use. There is no need to buy the latest edition.
