Summary: Add scattering to a ballistic system. One scattering site reduces current by transmission probability. Two scattering sites, transmission depends on wave interference.

Summary: Pair of inelastic scattering sites. See hw#3 for many inelastic scattering sites. Many elastic scattering sites. Anderson localization. Review of what we've covered so far. Temperature-dependent conductivity of lightly doped semiconductors. Gate-voltage-dependent conductivity of lightly doped semiconductors.
