学术成果
【学术表现】
长期基于对尺度模拟结合人工智能对新材料、材料物性及其内在性能机理展开系 统研究,至今取得了一系列国际领先的原创性研究成果。在低维材料物性方面,系统研究了一系列单分子磁体的磁性机制,发现了一种新的基于f轨道的磁直接相互作用。此外在方法上发展了一种新的基于多重散射理论的电子传输方法,并用之系统研究了基于石墨烯的新型场效应管的电子传输问题;在人工智能辅助设计材料方面,通过高通量计算建立了基于第一性原理计算的目前最大最广的金属晶界能数据库,并在著名数据库中心Materials Project发布。同时也是从事机器学习势函数这一新兴领域最早的学者之一,为机器学习势场推广到多元合金体系作出了重要的贡献。此外发展了一种基于原子结构图形化的预测材料禁带宽度的深度学习模型。此部分的研究得到了领域同行的广泛关注,多次受邀参加高水平国际会 议做邀请报告。至今发表学术论文60余篇,其中以第一/通讯作者身份在Nat. Commun.、Nano Lett.、npj Comput. Mater. 、Acta Mater.、Phys. Rev. B等高水平期刊发表研究论文18篇,累计引用3400余次。受邀担任 Nature 旗下计算 材料顶刊 npj Comput. Mater.客座编辑,已评审或仲裁物理顶刊 Phys. Rev. Lett.论文 15 篇以及其他材料和物理期刊Adv. Funct. Mater., npj Comput. Mater.等总计 60 余篇。回国以后一直担任深圳市科创委通讯评审专家。
