Abstract
Electrical, thermal properties, and transport mechanisms in Ge2Sb2Te5 (GST225) thin films were investigated. Crystallization temperature for thin films was estimated. It was established that investigated thin films have p-type conductivity. Temperature dependencies of the resistivity for investigated thin films were studied. Two-channel model of charge carrier transport was used for the modeling of the temperature dependencies of conductivities. Activation energies of conductivity, position of the trap level controlling transport mechanism, and the density of states for this level were estimated.
