Precursor, Substrate and Other Parties—In The Quest for Quality 2D-Commodity

2D materials synthesis has reached maturity stage when the challenge shifts from just “making something new” up to making it fast, at scale, and of defect-free highest quality, so to meet the needs and stringent standards of electronics manufacturing industry.<br/>● We will discuss how the theoretical insight and computational modeling help to reveal the molecular mechanisms of the reactions (mostly of CVD type), determine the gas phase precursor, optimal substrates in achieving the wafers-size monocrystal graphene, hexagonal boron nitrogen, free borophene phases, and the novel, better TMDs.<br/>● If time permits, we may also touch an intriguing topic of how to <i>define the crystal shapes</i>—so vividly seen for many 2D materials—when their edge energies are <i>fundamentally undefinable</i>, due to the lattice low symmetry.<br/>Supported by the DOE BES grant DE-SC0012547 and in part (case of BN) by the ARO grant W911NF1920269.
