This course focuses on the fundamentals of magnetic materials, semiconductor, dielectric materials and nano materials. Topics include microscopic origin of magnetism and dielectricity based on electronic structure theory, electronic conduction in the dielectrics, spin, band-theory, p-n junction and the application of these materials. The course enables students to understand and acquire the fundamentals of electronic materials.
Understanding the electronic materials such as magnetic materials, semiconductor, dielectric materials is the key to develop the state-of-the-art electronic devices. Comprehensive study of these materials allows students to think about the differences among these materials. I hope students have interests in the electronic phenomena in various materials.
By the end of this course, students will be able to:
1) Understand the origin of dielectric properties, dielectric constant and dielectric dispersion.
2) Explain the model of electronic conduction in the dielectrics and organic semiconductors.
3) Understand the origin of magnetism, magnetic properties such as ferromagnetism.
4) Give specific applications of magnetic materials.
5) Explain the energy band structure of semiconductor.
6) Explain the current voltage characteristic of pn junction.
