摘要：

The electrical properties of Ge5As38Te57 have been carried out as a function of temperature at different de electric fields for the bulk and thin films. This material shows a non-ohmic behaviour by switching to a negative resistance state. The activation energy was found to decrease slowly as the electric field increases and increases again before switching to the negative region. The conduction is simply a field-dependent hopping mobility at low fields. The high-field conduction mechanisms have been explained in terms of the Poole-Frenkel effect and Schottky emission of carriers which is applicable to both bulk and thin films.
