First-principles analysis of the effect of magnetic states on the oxygen vacancy formation energy in doped La$_{0.5}$Sr$_{0.5}$CoO$_3$ perovskite

Wei Wei, Florian Fuchs, Andreas Zienert, Xiao Hu et autres

Oxygen vacancies are critical for determining the electrochemical performance of fast oxygen ion conductors. The perovskite La$_{0.5}$Sr$_{0.5}$CoO$_3$, known for its excellent mixed ionic-electronic conduction, has attracted significant attention due to its favorable vacancy characteristics. In this study, we employ first-principles calculations to …

Selecting and Merging: Towards Adaptable and Scalable Named Entity Recognition with Large Language Models

Zhuojun Ding, Wei Wei, Chenghao Fan

Supervised fine-tuning (SFT) is widely used to align large language models (LLMs) with information extraction (IE) tasks, such as named entity recognition (NER). However, annotating such fine-grained labels and training domain-specific models is costly. Existing works typically train a unified model across …
