Charge transport in Sb-doped SnO2 nanoparticles studied by THz spectroscopy

Using terahertz spectroscopy we investigate the charge transport in Sb-doped SnO₂ nanoparticles pressed into pellets. Doped and undoped samples are shown to have different mechanisms of intrinsic conductivity. We systematically study the influence of annealing on intra- and inter-nanoparticle charge transport.
