Abstract

The electrical properties and structure of Te53-As36-Ge-11 chalcogenide glass were investigated with various conditions of heat treatment and preparation. This material was found to exhibit negative resistance with a memory and can be converted from high to low resistance state thermally by heating to a transition temperature or electrically by passing a transition current. The activation energy for conduction was found to be 0.36 and 0.3 eV in the high and low resistance states respectively.
