Evaluating the Structural Basis for Polar Altermagnet Candidate Ca(Ru,Ti)O
Akash Saha, Yihuang Xiong, Vladimir A. Stoica +15
The interplay between polar and altermagnetic orders remains largely unexplored in the broader landscape of correlated electron systems. CaRuO has been proposed b…
Short-range order in the CoCrFeMnNi high-entropy alloy from cluster expansion
Wei Chen, Gian-Marco Rignanese, Geoffroy Hautier
We investigate the short-range order (SRO) and phase stability of the equiatomic CoCrFeMnNi high-entropy alloy using cluster expansion supplemented by an eigen-decomposition analys…
Thin film synthesis of SrZn2P2 with SrI2 post-annealing for enhanced crystallinity and optoelectronic quality
Sita Dugu, Shaham Quadir, Christopher P. Muzzillo +11
Ternary Zintl phosphides are promising light-absorbing semiconductors for thin-film optoelectronic applications, but strategies for controlling their microstructure and optoelectro…
BaCd2P2: a promising impurity-tolerant counterpart of GaAs for photovoltaics
Gideon Kassa, Zhenkun Yuan, Muhammad R. Hasan +5
BaCd2P2 (BCP) has been recently identified as a new solar absorber with promising optoelectronic properties. This work demonstrates that, despite having a low precursor purity (98.…
Long photoexcited carrier lifetime in a stable and earth-abundant zinc polyphosphide
Zhenkun Yuan, Genevieve Amobi, Shaham Quadir +16
Halide perovskites have revolutionized optoelectronics by demonstrating that long carrier lifetime can be achieved in materials processed in relatively uncontrolled environments, w…
On The Finetuning of MLIPs Through the Lens of Iterated Maps With BPTT
Evan Dramko, Yizhi Zhu, Aleksandar Krivokapic +4
Accurate structural relaxation is critical for advanced materials design. Traditional approaches built on physics-derived first-principles calculations are computationally expensiv…
