23_45/2011Hybrid Light-Emitting Diodes: Electrically Driven Quantum Dot/Wire/Well Hybrid Light-Emitting Diodes (Adv. Mater. 45/2011)

Electrically driven hybrid light-emitting diodes (LEDs) consisting of quantum dots, wires, and wells based on the nanometer-sized pyramid GaN structure are reported by Taek Kim, Yong-Hoon Cho, and co-workers on page 5364. The LEDs exhibit mixed emissions from InGaN quantum dots, wires, and wells formed at the tops, edges, and sidewalls of the pyramids, respectively. The hybrid LEDs containing low-dimensional quantum structures provide a broad-band, highly efficient visible lighting source.
