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…
Inert gas as electronic impurity in semiconductors: The case for active infrared absorption in silicon
Nian-Ke Chen, Yu-Chen Gao, Ji-Hong Zhao +5
Inert (noble gas) elements are extremely inactive to surrounding chemical environment and are frequently employed as protective gas in various semiconductor fabrication processes.…
Photoinduced ultrafast transition of the local correlated structure in chalcogenide phase-change materials
Yingpeng Qi, Nianke Chen, Thomas Vasileiadis +4
Revealing the bonding and time-evolving atomic dynamics in functional materials with complex lattice structures can update the fundamental knowledge on rich physics therein, and al…
