2D non-van der Waals (vdW) Cr5Te8 has attracted widespread research interestfor its air stability and thickness-dependent magnetic properties. However,exploring new methods for growing larger-scale ultrathin 2D Cr5Te8 remainschallenging. Here, we selected GaTe powder as precursor to supply Te monomersand fabricated large-scale 2D Cr5Te8 nanosheets. By optimizing the growthtemperature and source-substrate distance (DSS), we successfully achievedCr5Te8 nanosheets with lateral sizes of up to ~0.19 mm and correspondingthicknesses down to ~4.8 nm. The role of GaTe enhances the efficient Te atomsconcentration, which promoted the lateral growth of Cr5Te8 nanosheets.Furthermore, our findings reveal the presence of Cr5Te8 nanosheets exhibitingserrated edges and a stacked structure like wedding cakes. Magnetic propertymeasurement revealed the intense out-of-plane ferromagnetism in Cr5Te8, withthe Curie temperature (TC) of 172 K. This work paves a way for the controllablegrowth of the submillimeter ultrathin 2D ferromagnetic crystalline and lays thefoundation for the future synthesis of millimeter ultrathin ferromagnets.
