An electrically driven structural phase transition in single Ag2Te nanowire devices
Exploring new phase-change materials is instrumental in the progression of electronic memory devices. Ag2Te with its reversible structural phase transition, and in the form of nanowires, has become an apt candidate for potential use in nanoscale memory devices. Here, we report a study on the tempera...

| description | Exploring new phase-change materials is instrumental in the progression of electronic memory devices. Ag2Te with its reversible structural phase transition, and in the form of nanowires, has become an apt candidate for potential use in nanoscale memory devices. Here, we report a study on the temperature- or electrically-driven phase change properties of crystalline Ag2Te nanowires. We first demonstrate that this structural phase change can be achieved via heating up the nanowires, which results in a sharp drop in conductance. Then we show that a DC voltage ( |
