Recently, we revealed the unprecedented high thermal stability offered by the novel chalcogenide phase-change GeSe1-xTex alloys. The latter is of paramount interest for non-volatile PCM memory requiring high-temperature data retention. Herein, we investigate for the first time the effect of N incorporation in Ge-Se-Te thin films. We show that the thermal and programming performances in device can be potentially boosted thanks to the addition of ∼10 at.% of nitrogen, making N-doped GeSe1-xTex an extremely promising material for embedded PCM memories.
