Abstract
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.
