University of Er of British snow humble (the group of a research of Sheffield University) is in recently " applied physics wall bulletin " (release in half polarity nitrogen to change gallium (on periodical of Applied Physics Letter)GaN) or grow on sapphirine base materialLEDnewest achievement.

Use what grow on M-Plane sapphirine substrateGaNPattern plate of production small post array, researcher can be excessive on its growth half polarityGaN(Grow on 11-22) issue those who have taller quanta beneficial resultLED.
relatively use at the business that grows on C-Plane sapphirine substrateLED, the green smooth LED that this research group grows on half polarity material shows glow to the blue displacement of wavelengh increases as drive electric current and decrease. The circumstance that observes in blue displacement place is applicable also go up in olivine and Huang Guang LED, accordingly, the LED that researcher discovers to place grows exists a kind of effect that restrain quanta effectively and limits astral dazzle.
Researcher is measured so that illuminant output shows linear along with voltaic promotion to increase on brilliant circle, and its are exterior quanta efficiency shows relatively the efficiency attenuation that business uses C-Plane LED (Efficiency-droop) circumstance already was improved apparently. Electroluminescence polarization measures the polarization that demonstrates half polarity LED to be than making an appointment with 25% .
Researcher claims, abecedarian result shows, excessive grow the technology is a kind of method that has potential cost effectiveness more, can be in longer the emitter of half polarity GaN that tall efficiency achieves in wavelengh area.
