Exciton-related electroluminescence from monolayer MoS2

, 2013
Excitons in MoS2 dominate the absorption and emission properties of the two-dimensional system. Here, we study the microscopic origin of the electroluminescence from monolayer MoS2 fabricated on a heavily p-type doped silicon substrate.

Electroluminescence from isolated defects in zinc oxide, towards electrically triggered single photon sources at room temperature

, 2015
Single photon sources are required for a wide range of applications in quantum information science, quantum cryptography and quantum communications. However, so far majority of room temperature emitters are only excited optically, which limits their proper integration into scalable devices.
