WebNov 13, 2024 · In materials science, the material’s band gap is an important property governing whether the material is metal or non-metal. In this study, we aim to use GCN to predict the band gap given the Hamiltonian of the material. Band gap is described by a nonnegative real number, E_g \in \mathbb {R} and E_g \ge 0. Webmany works [8, 35, 48, 25] regard molecules as graphs and explore the graph convolutional network for property prediction. To better capture the interactions among atoms, [8] proposes a message passing framework and [20, 48] extend this framework to model bond interactions. [25] builds a hierarchical GNN to capture multilevel interactions.
