Abstract

In article 1500290, X. C. Zeng and co-workers demonstrate simulation evidence for a structural transition in 2D ZnSe. The 2D tetragonal ZnSe monolayer exhibits highly tunable bandgap from 2 to 3 eV under the biaxial strain, suggesting its potential application as light-emitting material in red-green-blue light emission diodes or for visible-light driven water splitting through suitable band alignment.
