The electrical conductivity of silver nanowire assembly is measured by using terahertz spectroscopy. Growth of the surface-oxidized layer on silver nanowires hinders electron transportation through the nanowire-to-nanowire junction and reduces the conductivity of nanowire network.
We present a new model for the simulation of negative differential resistance (??snapback??) in a phase-change memory cell using an electrothermal finite-element iterative calculation implemented in ANSYS. This model improves upon our previous models by applying a double Arrhenius temperature-dependent resistivity for the amorphous chalcogenide, and a JMAK (n=3.5) model to describe the phase-change...
