Stimulated emission of excitons was observed at temperatures well above room temperature due to the adoption of the lattice-matched substrates. The mechanism of stimulated emission from ZnO quantum wells is discussed in this chapter.23 pages, 11 figures, for a book chapter, LaTeX articleMaterials Sciencetext
