2D materials have attracted considerable attention in the past decades for their unique properties, making the understanding of their nucleation process key to effective synthesis. Traditional explanations of thin-film growth, focusing on the competition between atom interactions at the interface and within layers, often fall short of explaining real experimental results. Herein, a penetrated nucleation mechanism is proposed for 2D materials growth on metal substrates, taking into account the role of metal substrate atoms. This approach leads to a better understanding of how the surface shape evolves in two specific ways during growth in real experimental findings. Supported by detailed first-principles simulations of boron on metal substrates and thermodynamic analyses of other studies involving metals and nonmetals, the above-proposed mechanism is validated. Moreover, a broad strategy for growing large-scale 2D materials on metal surfaces without creating undesired alloy layers is also presented, by adjusting the interfacial interactions by surface passivation, validated by existing experiments.
