主动学习已经越来越多地应用于从现有材料数据库中筛选具有所需性质的功能材料。然而,存放在流行的材料数据库(如ICSD和Materials Project)中的已知材料数量非常有限,仅占巨大化学设计空间的一小部分。本文提出了一种主动生成式逆设计方法,该方法将主动学习与深度变分自编码器神经网络和生成对抗深度神经网络模型相结合,以在整个化学设计空间中发现具有目标性质的新材料。该方法的应用使我们能够发现具有高带隙的新的化学稳定材料(SrYF $_5$)和具有特定带隙范围的半导体(SrClF $_3$,CaClF $_5$,YCl $_3$,SrC $_2$ F $_3$,AlSCl,As $_2$ O $_3$),所有这些都通过第一原理DFT计算验证。我们的实验表明,虽然主动学习本身可能会采样化学上不可行的候选人,这些样本有助于训练有效的筛选模型,用于从生成模型创建的假设材料中筛选出具有所需特性的材料。实验结果表明了该方法的有效性。
英文摘要:
Active learning has been increasingly applied to screening functional materials from existing materials databases with desired properties. However, the number of known materials deposited in the popular materials databases such as ICSD and Materials Project is extremely limited and consists of just a tiny portion of the vast chemical design space. Herein we present an active generative inverse design method that combines active learning with a deep variational autoencoder neural network and a generative adversarial deep neural network model to discover new materials with a target property in the whole chemical design space. The application of this method has allowed us to discover new thermodynamically stable materials with high band gap (SrYF$_5$) and semiconductors with specified band gap ranges (SrClF$_3$, CaClF$_5$, YCl$_3$, SrC$_2$F$_3$, AlSCl, As$_2$O$_3$), all of which are verified by the first principle DFT calculations. Our experiments show that while active learning itself may sample chemically infeasible candidates, these samples help to train effective screening models for filtering out materials with desired properties from the hypothetical materials created by the generative model. The experiments show the effectiveness of our active generative inverse design approach.
