Controlling hysteretic transitions in quasi-one-dimensional TiS3 microribbons

Understanding the occurrence of charge density wave (CDW) states in quasi-one-dimensional (quasi-1D) transition metal trichalcogenides has attracted substantial research interest. Here, we report the systematic control of hysteretic transitions in quasi-1D TiS3 microribbons by changing the thickness and the cooling rate. Two distinguished resistance hysteresis loops are observed at a high temperature of ~290 K and a low temperature of ~60 K, respectively. In addition, two hysteretic transitions exhibit different behaviors under the external perturbations, in which the high temperature hysteretic transition is sensitive to TiS3 microribbons thickness, while the low temperature hysteretic transition is probably related to the CDW state and is robust against external perturbations. Our findings will offer a new frontier of exploration of the hysteretic transitions in the quasi-1D transition metal trichalcogenides. Published under an exclusive license by AIP Publishing.

Automated summary

The study investigates the hysteretic transitions in quasi-1D TiS3 microribbons by controlling the thickness and cooling rate. Two resistance hysteresis loops are observed at high and low temperatures, respectively. The high temperature transition is sensitive to thickness, while the low temperature transition is likely related to the CDW state and is robust against external perturbations.
