摘要

The use of simpler compositions for phase-change memory has been a popular goal. This study explores phase-change, electrical conduction and thermal stability of Ga_(16)Sb_(84) film to meet this purpose. Amorphous Ga_(16)Sb_(84) film shows a crystallization temperature of 227 °C and a temperature for 10 year data retention of 148 °C. The density of the film increases 5% upon crystallization. Asteep resistance drop during crystallization arises mainly from the sharp increase in carrier concentration with p-type conduction. Ga_(16)Sb_(84) memory cells demonstrate set-reset switching at a pulse width of 10 ns and have a durability of >10~5 cycles.
