A Fast and Controlled Growth of Two-dimensional Layered ZrTe3 Nanoribbons by Chemical Vapor Deposition
Quasi-one-dimensional (1D)/two-dimensional (2D) ZrTe3 attracts intensive interests as a typical charge density wave (CDW)-bearing material physically. However, limited by high time consumption up to even weeks and less morphological controllability for conventional chemical vapor transport (CVT) synthesis of ZrTe3 bulks, it is highly desirable to develop feasible methods for fast and controlled ZrTe3 growth, while so far has not been demonstrated. In this work, we first demonstrated that ZrTe3 nanoribbons can be grown directly by a modified chemical vapor deposition (CVD) method. The growth time is significantly reduced to less than 90 min, and the size of ZrTe3 nanoribbons can be well tuned by controlling the growth time and growth temperature. Moreover, differing from most of the other transition metal trichalcogenides (TMTCs), we reveal that ZrTe3 nanoribbons exhibit a competing and synergistic magnetic property between its intrinsic diamagnetism and unexpected ferromagnetism, which can be interpreted by the structural imperfection and edge-states due to the reduced dimensionality. Such observable ferromagnetism might favor for exploring its spin-electronic applications.
