3D-nHD: A HydroDynamic model for trap-limited conduction in a 3D network

Analytical models for trap-limited conduction have successfully been applied to the case of phase-change memory devices, providing an effective interpretation of the main chargetransport properties of chalcogenide materials. However they have been derived under the simplified hypothesis of one-dimensional continuum systems, and their extension to realistic geometries is anything but trivial. In this work we exploit a three-dimensional model for trap-limited conduction that makes use of a non-linear resistance network to implement the transport processes of the analytical models. Results correctly compare to experimental data and connect the transport properties to detailed microscopic information.
