Abstract
Ga2Te3 is of great interest because of its memory and threshold switching properties and potential for memory device application. Here, device of TiN/Ga2Te3/TiN with two terminals was fabricated and its threshold switching was investigated. Current–voltage measurements showed the ovonic threshold switching of amorphous Ga2Te3 thin films at 300 K with a high switching speed of about 10 ns. AC pulse tests showed reliable switching endurance over 109 switching cycles with the selectivity of 103. Amorphous Ga2Te3 with outstanding stability is considered as potential materials for the selector devices of cross–point memory array.
