Transport & Recombination

This lecture covers the transport and recombination processes in large area electronic materials, focusing on topics such as recombination in dangling bonds, charge state representation, recombination in doped and undoped a-Si:H, total recombination, dark conductivity, primary and secondary photoconductivity, defect density, trapping conduction, and transient photoconductivity. The instructor discusses various characterization techniques, including steady-state photoconductivity, constant photocurrent measurement, and transient photocurrent spectroscopy, highlighting the importance of understanding recombination mechanisms in different semiconductor materials.
