Traditional Semiconductors in the Two-Dimensional Limit. Lucking, M. C., Xie, W., Choe, D., West, D., Lu, T., & Zhang, S. Physical Review Letters, 120(8):086101, February, 2018. ![Traditional Semiconductors in the Two-Dimensional Limit [link]](https://bibbase.org/img/filetypes/link.svg "link")
Paper doi abstract bibtex Interest in two-dimensional materials has exploded in recent years. Not only are they studied due to their novel electronic properties, such as the emergent Dirac fermion in graphene, but also as a new paradigm in which stacking layers of distinct two-dimensional materials may enable different functionality or devices. Here, through first-principles theory, we reveal a large new class of two-dimensional materials which are derived from traditional III-V, II-VI, and I-VII semiconductors. It is found that in the ultrathin limit the great majority of traditional binary semiconductors studied (a series of 28 semiconductors) are not only kinetically stable in a two-dimensional double layer honeycomb structure, but more energetically stable than the truncated wurtzite or zinc-blende structures associated with three dimensional bulk. These findings both greatly increase the landscape of two-dimensional materials and also demonstrate that in the double layer honeycomb form, even ordinary semiconductors, such as GaAs, can exhibit exotic topological properties.
