Description

This lecture covers the concept of drift mobility in electronic materials, focusing on the thermal activation of carriers, multiple trapping conduction, and the time evolution of trapping statistics. It also discusses the influence of band tails on drift mobility, as well as the measurement and analysis of band tails using techniques like XPS. The lecture concludes with an examination of band tail absorption processes and the emerging picture of band structures in materials like a-Si:H and IGZO.
