Bright excitons in black phosphorus

Excitons—neutral bound states of electron and hole pairs—are essential to the optoelectronic behavior of semiconductor materials. These “quasiparticles” are generated when incident light is absorbed by a semiconductor, and they can recombine to emit light. Understanding and controlling excitonic behavior is therefore crucial to advancing nanophotonic and quantum optoelectronic technologies. However, presently available materials for such devices often do not exhibit a strong-enough interaction with light and lack tunability. On page 526 of this issue, Huang et al. (1) report the unexpected emergence of strong dipolar excitons in twisted multilayers of black phosphorus. This material exhibits tunable excitonic properties, which could unlock new quantum phenomena and shape future technologies.

期刊介绍： Science is a leading outlet for scientific news, commentary, and cutting-edge research. Through its print and online incarnations, Science reaches an estimated worldwide readership of more than one million. Science’s authorship is global too, and its articles consistently rank among the world's most cited research. Science serves as a forum for discussion of important issues related to the advancement of science by publishing material on which a consensus has been reached as well as including the presentation of minority or conflicting points of view. Accordingly, all articles published in Science—including editorials, news and comment, and book reviews—are signed and reflect the individual views of the authors and not official points of view adopted by AAAS or the institutions with which the authors are affiliated. Science seeks to publish those papers that are most influential in their fields or across fields and that will significantly advance scientific understanding. Selected papers should present novel and broadly important data, syntheses, or concepts. They should merit recognition by the wider scientific community and general public provided by publication in Science, beyond that provided by specialty journals. Science welcomes submissions from all fields of science and from any source. The editors are committed to the prompt evaluation and publication of submitted papers while upholding high standards that support reproducibility of published research. Science is published weekly; selected papers are published online ahead of print.
