Black phosphorus

A new bandgap tuning knob

Nature Photonics volume 11, pages 407–409 (2017)Cite this article

Subjects

An external 'tuning knob' by means of applying a transverse electric field has been experimentally demonstrated to modify the bandgap of black phosphorus, making the two-dimensional material practical for integration in functional nanodevices.
