Abstract:	摘要： The miniaturization of future electronic devices requires the knowledge of interfacial properties between two-dimensional channel materials and high- κ dielectrics in the limit of one atomic layer thickness. In this report, by combining particle-swarm optimization method with first-principles calculations, we present a detailed study of structural, electronic, mechanical, and dielectric properties of Al 2 O 3 monolayer. We predict that planar Al 2 O 3 monolayer is globally stable with a direct band gap of 5.99 eV and thermal stability up to 1100 K. The stability of this high- κ oxide monolayer can be enhanced by substrates such as graphene, for which the interfacial interaction is found to be weak. The band offsets between the Al 2 O 3 monolayer and graphene are large enough for electronic applications. Our results not only predict a stable high- κ oxide monolayer, but also improve the understanding of interfacial properties between a high- κ dielectric monolayer and two-dimensional material. 其他題名： Sci Rep 出版者： London: Nature Publishing Group UK 出版日期： 2016-07-06 出處： Scientific reports, 2016-07, Vol.6 (1), p.29221, Article 29221 資源來源： Springer Nature Link 版權： The Author(s) 2016 版權： Copyright Nature Publishing Group Jul 2016 版權： Copyright © 2016, Macmillan Publishers Limited 2016 Macmillan Publishers Limited 識別號： ISSN: 2045-2322 識別號： EISSN: 2045-2322 識別號： DOI: 10.1038/srep29221 識別號： PMID: 27381580
