新AI框架高精度预测材料能带结构

研究人员开发了O-kRystal,一个新颖的双空间轨道学习框架,用于预测材料准确的电子能带结构。该方法利用成本较低的Perdew-Burke-Ernzerhof (PBE)计算来提供结构化的轨道信息和能量基线。通过结合PBE数据与实空间和倒空间轨道矩阵,O-kRystal可以预测更高级别的修正,在5 eV的带边中点范围内,在多种材料上实现了Heyd-Scuseria-Ernzerhof (HSE06)能带能量的平均绝对误差为0.171 eV。该框架还展示了通过二维材料的$G_0W_0$准粒子能量,预测超越密度泛函理论的电子结构的潜力。 AI

影响 这种由AI驱动的方法可以通过降低预测电子属性的计算成本来加速材料发现。
