摘要

二硒化钛器件的相变在2418557号文章中，吴文伟等人利用原位透射电镜系统地研究了二硒化钛器件的相变。他们的研究揭示了由钛自插层驱动的偏置诱导相变，从六边形TiSe2过渡到正交Ti9Se2导电相。这些发现为1T-TiSe2的结构和电子动力学提供了有价值的见解，突出了其未来在基于电荷密度波的器件中的应用潜力。

Titanium Self-Intercalation in Titanium Diselenide Devices: Insights from In Situ Transmission Electron Microscopy (Adv. Mater. 17/2025)

Phase Transformation of Titanium Diselenide Devices

In article number 2418557, Wen-Wei Wu, and co-workers systematically investigate the phase transformation of titanium diselenide devices using in-situ transmission electron microscopy. Their study reveals a bias-induced phase transformation driven by titanium self-intercalation, transitioning from hexagonal TiSe₂ to the orthorhombic Ti₉Se₂ conducting phase. These findings offer valuable insights into the structural and electronic dynamics of 1T-TiSe₂, highlighting its potential for future applications in charge-density-waves-based devices.
