Nevertheless, it is still challenging to grow high-quality 2D TMTs with the desired phase (especially high-temperature phase) because of the weak bonding between the transition metal and Te as compared to S and Se atoms. Here, a strategy of siliconizing-driven layer-by-layer growth is reported to synthesize 2D ZrTe2 and ZrTe3 crystals with high crystallinity and desired thickness. Both as-synthesized crystals exhibit large-area uniform phases and atomically precise layered stacking structures. 2D ZrTe2 shows type-II Weyl semimetal characteristics with negative magnetoresistance, and 2D ZrTe3 demonstrates the existence of charge density waves and intrinsic superconductivity. Theoretical study reveals that silicon atoms can infiltrate and isolate a single layer of zirconium atoms and allow them to be tellurized in a layer-by-layer manner.
