数据挖掘和加速电子结构理论作为寻找新功能材料的工具

Data mining and accelerated electronic structure theory as a tool in the search for new functional materials

C. Ortiz, O. Eriksson, M. Klintenberg

摘要:

数据挖掘是一种公认的预测工具,在各种领域,从生物信息学和药物设计到晶体结构预测。在本研究中,电子结构的实现已经与无机晶体结构数据库的结构数据相结合,以产生约22,000种无机化合物的高加速电子结构计算结果。它示出了如何在数据库上采用的数据挖掘算法可以识别新的功能材料与所需的材料特性,从而在136个新的材料与潜在的电离辐射探测器材料的预测。介绍了自动化从头算方法背后的方法,将结果制成表格,并在互联网网站http://gurka.fysik.uu.se/ESP/(参考文献1)上提供了完整数据库的版本。

英文摘要:

Data mining is a recognized predictive tool in a variety of areas ranging from bioinformatics and drug design to crystal structure prediction. In the present study, an electronic structure implementation has been combined with structural data from the Inorganic Crystal Structure Database to generate results for highly accelerated electronic structure calculations of about 22,000 inorganic compounds. It is shown how data mining algorithms employed on the database can identify new functional materials with desired materials properties, resulting in a prediction of 136 novel materials with potential for use as detector materials for ionizing radiation. The methodology behind the automatized ab-initio approach is presented, results are tabulated and a version of the complete database is made available at the internet web site http://gurka.fysik.uu.se/ESP/ (Ref.1).
