ENSC3014 Electronic Materials and Devices 2024 Conductivity Module B Brett Nener Outline ENSC3014 WebThe Drude-Smith model has been used extensively in fitting the THz conductivities of nanomaterials with carrier confinement on the mesoscopic scale. Here, we show that the conventional “backscattering” explanation for the suppression of low-frequency conductivities in the Drude-Smith model is not consistent with a confined
WebWhile the Drude-Smith model has been shown to describe the terahertz (THz) conductivity in a variety of nanomaterials,^1,2 its validity and physicality have been questioned. We present a refinement to the backscattering interpretation of the Drude-Smith model, which is shown to emerge analytically from a structurally confined Drude gas of electrons. Web3. Procedure for the Drude-Smith model Similar as for the LMD model, we account for interband transitions but not vibrations for the Drude-Smith model, and use a single fit for the full spectral range. Although the permittivity dispersion curve of the Drude-Smith model is similar to the other two models, the extracted parameters are quite
