A guideline for designing chalcogenide-based glasses for threshold switching characteristics

Chalcogenide-based switching materials have potential applications in power control and information storage. In this work, an approach has been suggested to design chalcogenide-based amorphous materials for threshold or memory switching characteristics. Using this guideline, glasses have been formed in a new chalcogenide Al-Ge-As-Te system. All the samples studied have been found to exhibit threshold switching characteristics, which proves the validity of the suggested guideline.
