Reveals the microscopic origin of the super-cooled NCCDW phase in tantalum disulfide nanocrystals, highlighting its unique structural properties.
Key Points
The aim is to understand the atomic-scale structure and origins of the super-cooled nearly commensurate charge density wave (SC-NCCDW) phase in 1T-TaS₂.
Conducted electrical transport measurements
Performed temperature-dependent X-ray diffraction
Utilized high-resolution transmission electron microscopy (HR-TEM)
Rapid cooling stabilizes the SC-NCCDW state
Lattice-volume expansion occurs during the NCCDW-to-CCDW transition under gradual cooling
Rapid cooling creates a mixed-phase configuration showing features of both NCCDW and CCDW phases
