Unconventional crystallization pathway bypassing the intermediate cubic phase in phase-change superlattices
Bai-Qian Wang, Nian-Ke Chen, Yao-Jie Wang +5
The Ge-Sb-Te (GST) superlattice phase-change material is a promising candidate for overcoming the high power-consumption of phase-change memory (PCM). However, the working mechanis…

Electronic excitation of ultrafast collective amorphous-amorphous transitions in glassy phase-change material
Yingpeng Qi, Nianke Chen, Zhihui Zhou +10
The intrinsic nature of glass states and glass transitions remain a fundamental open question in condensed-matter physics and materials science. The key to solving the glass transi…
