Benchmarking model chemistry composite calculations for vertical ionization potential of molecular systems

Chinese Chemical Letters 2025年第2期36卷 536-539页

In chemical science, the vertical ionization potential(VIP) is a crucial metric for understanding the electronegativity, hardness and softness of chemical material systems as well as the electronic structure and stability of molecules. Ever since the last century, the model chemistry composite methods have witnessed tremendous developments in computing the thermodynamic properties as well as the barrier heights. However, their performance in realm of the vertical electron processes of molecular systems has been rarely explored. In this study, we for the first time benchmarked the model chemistry composite methods(e.g., CBS-QB3, G4 and W1BD) in comparison with the commonly used Koopmans' s theorem(KT), electron propagator theory(e.g., OVGF, D2, P3 and P3+) and CCSD(T) methods in calculating the VIP for up to 613 molecular systems with available experimental measurements. The large-scale test calculations strongly showed that the CBS-QB3 model chemistry composite technique can be well recommended to calculate VIP from the perspectives of accuracy, economy and applicability. Notably, the VIP values of up to 7 molecules were identified to have the absolute errors of larger than 0.3 e V at all calculation levels,which have strong hints that their VIP experimental values should be re-investigated.

Optimizing large optical contrast in Ge-Se-Te films via high-throughput method

引用

Progress in Natural science:materials International 2025年第01期 222-228页

作者： Qiqi Chen Guoxiang Wang Zijun Liu Yixiao Gao Chenjie Gu Tiefeng Xu Xiang Shen Yimin Chen Laboratory of Infrared material and Devices & Key Laboratory of Photoelectric materials and Devices of zhejiang Province Advanced Technology Research InstituteNingbo University Department of Microelectronic science and engineering School of Physical Science and Technology Ningbo University Ningbo Solartrum Co.Ltd.

Chalcogenide phase-change materials（PCMs） have attracted great attentions due to their potential applications in reconfigurable photonic devices. The Ge2Sb2Te5and GeTe PCMs exhibit significant difference in refractive index（Δn） between amorphous and crystalline states, but they suffer from high optical loss. The binary Sb2S3and Sb2Se3PCMs, however, show low optical loss but small Δn. This encourages us to develop the novel materials,which are desired to combine large Δn and low optical loss. Instead of traditional trial-and-error screening method, we here used an efficient high-throughput method to optimize the PCMs' candidates for reconfigurable photonic devices in Ge-Se-Te chalcogenides. The crystallization temperature and difference in optical bandgap were detected, and then the component of Ge25Se7Te68, which also exhibits ultralow optical loss of 1.2 × 10-6（in amorphous state） and large Δn of 1.32 at 1550 nm, was optimized. This Te-rich Ge-Se-Te film can be a candidate for the applications of programmable reconfigurable photonic circuits.
