Caption

Figure 3 (a) Without a tunnel junction, current flows toward the bottom of the electrode and excites the quantum dot; however, the electrode obstructs light extraction. (b) In the presence of a tunnel junction, the current path can be redirected electrode-free regions, facilitating light extraction.
