Introductory description

To present, in context, the fundamental properties of semiconductor materials and devices. Students will study
fundamental aspects and the theory that underpins semiconductor material properties and how these link to device operation. Students will also study electronic structure theory, electronic transport theory, basic principles of low-dimensional nanodevices; basic principles of advanced and novel electronic devices; and the basics of semiconductor material and device simulation. The aim being to provide advanced understanding into semiconductor material and devices, beyond what is taught in undergraduate studies.
