Perturbation of charge density waves in 1T-TiSe
arXiv:2102.02559 · doi:10.1103/PhysRevB.103.125430
Abstract
In this study, using low-temperature scanning tunneling microscopy (STM), we focus on understanding the native defects in pristine \textit{1T}-TiSe at the atomic scale. We probe how they perturb the charge density waves (CDWs) and lead to local domain formation. These defects influence the correlation length of CDWs. We establish a connection between suppression of CDWs, Ti intercalation, and show how this supports the exciton condensation model of CDW formation in \textit{1T}-TiSe.
