However, the recently discovered ultrathin van der Waals ferroelectric Bi2SeO5 exhibits robust… Experiment Bi₂O₂Se https://arxiv.org/abs/2512.10786v2 https://arxiv.org/abs/2512.10786v2 Thu, 11 Dec 2025 16:29:48 GMT arXiv: Two-dimensional (2D) materials could overcome the scaling bottleneck of nanoelectronics by enabling atomically thin channels, superior electrostatic control, and reduced short-channel effects. However, progress is limited by the lack of semiconductor–insulator interfaces being simultaneously scalable, stable, and… Engineering Experiment Bi₂O₂Se https://arxiv.org/abs/2512.01284v1 https://arxiv.org/abs/2512.01284v1 Mon, 01 Dec 2025 05:03:03 GMT arXiv: As a newly identified single-crystalline van der Waals dielectric with a high dielectric constant, Bi2SeO5 plays a pivotal role in advancing 2D electronic devices. In this work, we systematically investigate the defect properties of Bi2SeO5 using first-principles calculations based on a hybrid functional. Although… Theory Bi₂O₂Se
