Field Dependent Conductivity and Threshold Switching in Amorphous Chalcogenides -- Modeling and Simulations of Ovonic Threshold Switches and Phase Change Memory Devices

Jake Scoggin, Helena Silva, Ali Gokirmak

We model electrical conductivity in metastable amorphous $G{e}_{2}S{b}_{2}T{e}_5$ using independent contributions from temperature and electric field to simulate phase change memory de…
