NANOSCIENCE & NANOTECHNOLOGY - 2022/3

Module Overview

Expected prior learning:  Students should have an interest in materials and devices.




Module purpose:  Nanotechnology promises new strong and light materials, faster electronic devices which consume less energy and have enhanced functionality. Nanotechnology and nanomaterials are everywhere; it is on the nanometer scale that many of the well-known descriptions and properties of materials breakdown and where an understanding of quantum effects becomes vital.  New materials such as graphene and carbon nanotubes with outstanding physical and electronic properties have emerged. This module will introduce quantum engineering and new nanomaterials as well as showing how developments have led to unprecedented ability to see and manipulate atoms and materials on the nanoscale.

5. Crystal lattices: planes and orientations in space, Miller indices.

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. A four hour written examination paper will assess knowledge of fundamental quantum and material properties and allow the student to demonstrate an ability to perform numerical calculations of key material parameters.  The assignment will assess the student’s ability to research into properties and applications of new materials. Thus, the summative assessment for this module consists of the following:

·         One 4-hour, open book written examination (worth 80% of the module)

·         One written assignment covering aspects associated with new materials and problem solving (worth 20% of the module).  The assignment is usually set in week 2 and is usually due week 9.

 

Any deadline given here is indicative. For confirmation of exact date and time, please check the Departmental assessment calendar issued to you.

 

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/model solutions)

·         Via assessed coursework

 

Module aims

• This module will equip students with an understanding of the science and engineering considerations that take place on the nanometer scale as well as developing an appreciation of the current status of, and future prospects for, nanotechnology. The module will show how quantum effects control many of the properties of materials and how the properties of new nanomaterials can be assessed using a range of techniques. 

Learning outcomes

Methods of Teaching / Learning

The learning and teaching strategy is designed to achieve the following aims.

1. Through the introduction of the key concepts, representative examples and in-class calculations, the students will be able to relate the properties of materials when quantum effects are considered.


2. Through the introduction, discussion and study of different materials, students will be able to examine and calculate the key properties of new materials.


3. Through the use of a revision and study questions with full solutions, student will be able to pace their own learning in parallel with the lecture course.

• Lectures and problem classes  


• Revision sessions  

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.
