ANTIMONY SURFACTANT EFFECT ON GREEN EMISSION InGaN/GaN MULTI QUANTUM WELLS GROWN BY MOCVD |
초록 |
An improvement in the optical and structural properties of green emitting InGaN/GaN Multi Quantum Wells (MQWs) was obtained by using antimony (Sb) as a surfactant during InGaN growth. Keeping the growth conditions for InGaN constant, Sb was introduced during InGaN growth while varying the [Sb]/([In]+[Ga]) flow ratio from 0 to 0.16%. The analysis results suggest that using the optimum [Sb]/([In]+[Ga]) ratio (0.04%-0.1%) during InGaN growth greatly improves the optical and structural properties of the MQWs without incorporating much Sb into the growing film and that the emission wavelength is also maintained with a slight blue shift. |
