Anisotropic Short-Range Order Modulates Ferroelectric Switching in Wurtzite ScAlN Alloys
Shunda Chen, Xianchao Dong, Xiaochen Jin +1
Ferroelectric switching in wurtzite alloys is typically understood in terms of composition, strain, defects, and interfaces, while local chemical order is often neglected or treate…
Shining light on short-range atomic ordering in semiconductors alloys
Anis Attiaoui, Shunda Chen, Joseph C. Woicik +7
The functional properties of semiconductors are typically controlled by tailoring their chemical composition and their state of strain, and by controlling their long-range structur…
Semiconductor-compatible topological digital alloys
Yunfan Liang, Damien West, Shunda Chen +3
Recently, GeSn alloys have attracted much interest for direct-gap infrared photonics and as potential topological materials which are compatible with the semiconductor industry. Ho…
Metastability and Ostwald Step Rule in the Crystallisation of Diamond and Graphite from Molten Carbon
Davide Donadio, Margaret L. Berrens, Wanyu Zhao +2
The crystallisation of carbon from the melt under extreme conditions is highly relevant to earth and planetary science, materials manufacturing, and nuclear fusion research. The th…
Atomic short-range order: a new degree of freedom for band engineering of GeSn semiconductor alloys
Shang Liu, Yunfan Liang, Nirosh M. Eldose +18
Chemical short-range order (SRO) in alloys denotes the statistical preference or avoidance between atomic species on neighboring lattice sites. Here, we highlight SRO as a powerful…
