Dissemination of IT for the Promotion of Materials Science (DoITPoMS)

DoITPoMS TLP Library

TLP Library

Teaching and learning packages (TLPs) are self-contained, interactive resources, each focusing on one area of Materials Science.

TLPs containing HTML5 animations/simulations are labelled with the tag . We have found that often the HTML5 animations render better in Microsoft Edge, so if your favourite browser does not work very well with them, please try an alternative.

Brillouin Zones

This teaching and learning package provides an introduction to Brillouin zones in two and three dimensions and is aimed at developing familiarity with Brillouin Zones. It will not cover any specific applications. Brillouin Zones are particularly useful in understanding the electronic and thermal properties of crystalline solids.

Crystallographic Texture

This teaching and learning package (TLP) introduces the concept of texture in crystalline materials such as common metals and metallic alloys.


Crystalline materials are characterised by a regular atomic structure that repeats itself in all three dimensions. In other words the structure displays translational symmetry.

Dielectric Materials

This teaching and learning package will introduce you to the properties and uses of dielectric materials.


Electromigration is an ever-increasing problem as integrated circuits are pushed towards further miniaturization. The theory of the phenomenon is explained, including electromigration-induced failure and how it has been and can be minimized.

Ferroelectric Materials

Ferroelectrics have been used in real-world applications for a small number of decades, most notably for non-volatile data storage. For example, they have been used in a Sony Playstation and Japanese railway cards.

Lattice Planes and Miller Indices

This teaching and learning package provides an introduction to the method used to describe planes of atoms in a crystalline material. The practical uses of describing planes of atoms are also addressed.

Piezoelectric Materials

This teaching and learning package (TLP) provides an introduction to piezoelectric materials.

Pyroelectric Materials

Pyroelectric materials are found in almost every home, in the form of intrusion detectors and other devices, and this TLP will consider how they work, and what the most common ones are made of.

Introduction To Semiconductors

This teaching and learning package provides a very basic introduction to semiconductors. These materials are essential to the operation of solid state electronic devices.

Slip in Single Crystals

This teaching and learning package explains how plastic deformation of materials occurs through the mechanism of slip. Slip involves dislocation glide on particular slip planes. The geometry of slip is explained, and electron microscopy techniques are used to show slip occurring in single crystals of cadmium.

The Stereographic Projection

This TLP covers the use of the Stereographic projection and Wulff nets.


Electrons in pairs? Levitating trains? Superconductivity - the combination of lossless electrical conduction and the ability of a material to expel a magnetic field - is a property that excites interest in fundamental science whilst offering tantalising prospects for a range of applications. In this teaching and learning package (TLP), we trace the history of superconductivity, outline some fundamental properties of superconductors, and describe current and potential applications of materials with this unusual property.

X-ray Diffraction Techniques

This teaching & learning package provides an introduction to X-ray diffraction. It describes the main crystallographic information that can be obtained and experimental methods most commonly used.
