Charge Transport in Low Dimensional Systems
This lecture covers the fundamentals of charge transport in semiconductors, focusing on the Drude model and its application to semiconductors, the behavior of electrons and holes as charge carriers, and the electrical transport in low dimensional semiconductors like GaAs and AIGaAs. It also discusses the engineering of 2D Electron Gas (2DEG), the tuning of dispersion relation, quantum conductance, Coulomb blockade, and the quantum Hall effect in 2DEG. The lecture concludes with a discussion on the measurement of Hall resistance in 2DEG and the quantum conductance of a Coulomb blockade.
