Atomically Thin Semiconductors
In article number 2102893, Junsuk Rho, Kyoung‐Duck Park, and co‐workers develop a triple‐sharp‐tips nano‐antenna to facilitate radiative emissions of the localized states in 2D semiconductors. The localized exciton is deterministically induced and probed at room temperature through this novel concept of tip‐enhanced cavity‐spectroscopy. This new approach provides a practical way to control single‐photon generation at room temperature, which is the centerpiece of quantum optical communications.
