dc.description.abstract | We investigate the effect of charge-charge interactions on carrier mobility in titanium dioxide (TiO2) and silicon (Si) using terahertz spectroscopy. Charge scattering times and plasma frequencies are directly determined as a function of charge density. In Si, a linear increase in scattering rate for densities exceeding 1021 m−3 is attributed to electron-hole scattering. In contrast, in TiO2, charge-charge interactions are suppressed due to dielectric screening, highlighting the vastly different dielectric properties for these two materials. | en_GB |
