The course is based on modern views on the structure of solids, how that structure is determined by X-ray crystallography and the basics of structure-property relationships. This involves learning the language of the basic shapes and symmetry displayed by crystals, then using that within the interdisciplinary subject of X-ray crystallography, source of many Nobel prizes and great advance in Physics, Chemistry, Materials Science, Biology and Medicine. The course then briefly examines some key topics including semiconductors, defects and amorphous materials.
|Session||First Sub Session||Credit Points||15 credits (7.5 ECTS credits)|
The course begins at the basics of describing crystalline solids, taking in shapes and symmetry, and moving on to a thorough coverage of diffraction methods (X-ray, neutron and electron) and how they are used to describe crystalline materials. Workshop will develop these ideas into 3-dimensional symmetry and how this can be described mathematically. From the study of perfect crystals, the course will touch on non-crystalline solids and defects in crystals, naturally developing into the basic ideas of doping in semiconductors. Quasicrystals, liquid crystals and photonic crystals will also be introduced within the framework of structural descriptions and diffraction. Effects of strain and particle size will also be explored. The concept of reciprocal space will be developed and linked back into the basics of X-ray crystallography.
This is the total time spent in lectures, tutorials and other class teaching.
1st Attempt: 1 one and a half hour written examination (60%), in-course assessment - based on workshops and online assessment (40%).
Online quiz (which provides detailed feedback on answers) taken more than once with best mark counting, thus acting as formative as well as summative assessment.
