FIG. 3.14 Structure of typical III-nitride LEDs. Device operation depends on the lateral current injection. The buffer layer is grown on a substrate at low temperatures to accommodate high lattice mismatch. (a) InGaN MQW-based LEDs for blue/green/yellow LEDs. AlGaN-based electron blocking layer is used to prevent injected electrons from escaping the active region. (b) AlGaN MQW-based UV LEDs. p-GaN is grown on p-AlGaN to prevent oxidation of aluminum.

..., we discuss the III-nitride compound semiconductors and the relevant devices such as solid light-emitting diodes (LEDs) and high electron mobility transistors (HEMTs). While addressing the specific problems/challenges prevalent in a semiconductor, we first discuss several aspects of thin-film growth...
