Limiting Efficiency
It has been well established that the limiting efficiency of single crystals falls at about 29% [Swanson] this limit was established in the seminal work by Tiedje. In figure 1 we can see this limiting efficiency [...]

Chemical solution deposition is a low-temperature and possibly the lowest-cost method of growing ZnO nanorods on a GaN substrate. However, most reported methods leave an interface layer between the grown ZnO nanorods and substrate, which can interfere with light emission and extraction. Here we [...]
