摘要
A new physical conductivity model of amorphous chalcogenide is proposed, based on carriers transport theory including hopping transport and trap-to-band transition. A numerical simulator based on this model is developed, and the simulation results agree well with the measurement. The ovonic switch voltage and current with different active area and temperature are studied based on the simulator, and the results show a good consistence with the measurement.
