“…20 In particular, doping proves to be a particularly simple and controllable approach to changing the bandgap size, shiing the position of the Fermi level and inuencing the type of charge carriers and thus regulating electronic, optical and magnetic properties. 21,22 Modern semiconductor technology is based on theoretical research and technical advances in semiconductor doping. In the eld of 2D materials, they are extremely sensitive to external factors due to their unique structure, where almost all atoms are exposed on the surface.…”

Two-dimensional (2D) Fe 3 Sn 2 , which is a roomtemperature ferromagnetic kagome metal, has potential applications in spintronic devices. However, the systematic synthesis and magnetic study of 2D Fe 3 Sn 2 single crystals have rarely been reported. Here we have synthesized 2D hexagonal and triangular Fe 3 Sn 2 nanosheets by controlling the amount of FeCl 2 precursors in the chemical vapor deposition (CVD) method. It is found that the hexagonal Fe 3 Sn 2 nanosheets exist with Fe vacancy defects and show no obvious coercivity. While the triangular Fe 3 Sn 2 nanosheet has obvious hysteresis loops at room temperature, its coercivity first increases and then remains stable with an increase in temperature, which should result from the competition of the thermal activation mechanism and spin direction rotation mechanism. A first-principles calculation study shows that the Fe vacancy defects in Fe 3 Sn 2 can increase the distances between Fe atoms and weaken the ferromagnetism of Fe 3 Sn 2 . The resulting 2D Fe 3 Sn 2 nanosheets provide a new choice for spintronic devices.

As for nonlayered 2D polymorphic materials, especially for Cr‐based chalcogenides, large‐area thin film growth with phase control is considered the most important synthesis challenge for magnetic, electronic, and optoelectronic devices. However, the synthesis methods of large continuous thin films for nonlayered 2D materials are still limited and rarely reported, also for the phase control growth, which is inhibited by isotropic 3D growth and similar Gibbs free energy for different phases. Herein, enhanced mass transport chemical vapor deposition is established to achieve the control synthesis of trigonal Cr2S3 thin films, in which the stable boundary layer supplies the continuous reaction species and tunes the reaction kinetics. The trigonal phase formation is confirmed by atomic structure characterization, optical absorption and piezoelectric measurements, demonstrating unique physical properties different from rhombohedral phase. The trigonal Cr2S3 thin films show obvious layer independent and dissimilar angle‐resolved harmonic generation, indicating the surface broken symmetry that can be understood by the combination of negligible piezoelectric response for bulk. The work presents the large‐area synthesized strategy by the modification of mass transport for nonlayered 2D materials with new phase formation and establishes the surface symmetry breaking dominated SHG mechanism for future nonlinear optical materials.
