    摘要: A light emitting device with a coupled quantum well structure in an active region. The coupled quantum well structure may include two or more wells are separated by one or more mini-barriers, and the wells and mini-barriers together are sandwiched by barriers. The coupled quantum well structure provides almost the same effect as a wide quantum well, due to the coupling of the wavefunctions through the mini-barrier. The light emitting device may be a nonpolar, semipolar or polar (Al,Ga,In)N based light emitting device.

    摘要: A method for photoelectrochemical (PEC) etching of a p-type gallium nitride (GaN) layer of a heterostructure, comprising using an internal bias in a semiconductor structure to prevent electrons from reaching a surface of the p-type layer, and to promote holes reaching the surface of the p-type layer, wherein the semiconductor structure includes the p-type layer, an active layer for absorbing PEC illumination, and an n-type layer.
