摘要： A method for growing an In(x)Al(y)Ga(1−x−y)N layer (where x is greater than zero and less than or equal to one, y is greater than or equal to zero and less than or equal to one and the sum of x and y is less than or equal to one). The method includes supplying plasma-activated nitrogen atoms as a source of nitrogen for the In(x)Al(y)Ga(1−x−y)N layer to a growth surface, where a flux of the plasma-activated nitrogen atoms supplied to the growth surface is at least four times higher than a total flux of aluminium and gallium atoms also supplied to the growth surface, where either the aluminium or gallium flux may or may not be zero; and simultaneously supplying indium atoms and nitrogen-containing molecules to the growth surface.

摘要： A nitride light emitting device (LED) according to a non-limiting embodiment of the present invention may include a p-pad and an n-pad, wherein the p-pad and n-pad are disposed on opposite ends of the device. A first p-branch electrode and a second p-branch electrode may extend from the p-pad toward the n-pad, with the first p-branch electrode extending along a length of the device. The second p-branch electrode may have a bent portion so as to extend along a width and length of the device. An n-branch electrode may extend from the n-pad toward the p-pad, wherein a distal end of the n-branch electrode is angled toward the bent portion of the second p-branch electrode. Alternatively, the p-branch and n-branch electrodes may be configured such that a distance between the n-branch electrode and the first and second p-branch electrodes increases with proximity to the n-pad. As a result, the nitride-based LED according to example embodiments may exhibit improved current uniformity, lower forward operating voltage, and higher overall efficiency.
