摘要

W-Sb-Te phase-change material has been proposed to improve the performance of phase-change memory (PCM). Crystallization temperature, crystalline resistance, and 10-year data retention of Sb ₂Te increase markedly by W doping. The W _x(Sb ₂Te) _1-x films crystallize quickly into a stable hexagonal phase with W uniformly distributing in the crystal lattice, which ensures faster SET speed and better operation stability for the application in practical device. PCM device based on W _0.07(Sb ₂Te) _0.93 shows ultrafast SET operation (6 ns) and good endurance (1.8 × 10 ⁵ cycles). W-Sb-Te material is a promising candidate for the trade-off between programming speed and data retention.
