Review of electron and photon properties. Electrons in 1-D potential well and potential barrier. Fundamentals: hydrogen atoms, bonds, crystal structures, concept of band theory of solids, effective mass, and the Fermi energy. Conduction in semiconductors: intrinsic extrinsic, drift, mobility, diffusion, recombination, Hall effect. Junctions: metal/semiconductor, p/n, breakdown, MOS capacitor. Brief introduction to transistors: MOSFET, JFET. Brief introduction to IC fabrication: layer formation, photolithography, layout. (Not for students who have taken ELEG2510 or ESTR3204.)
