    摘要: A method for making an epitaxial base includes the following steps. A plurality of grooves and a plurality of bulges are formed on an epitaxial growth surface of a substrate by etching the epitaxial growth surface. A carbon nanotube layer is located on the epitaxial growth surface, wherein the carbon nanotube layer defines a first part attached on top surface of bulges, and a second part suspended on the grooves. The second part of the carbon nanotube layer is attached on bottom surface of the grooves by treating the carbon nanotube layer.

    摘要: A method of growing an AlGaN semiconductor material utilizes an excess of Ga above the stoichiometric amount typically used. The excess Ga results in the formation of band structure potential fluctuations that improve the efficiency of radiative recombination and increase light generation of optoelectronic devices, in particular ultraviolet light emitting diodes, made using the method. Several improvements in UV LED design and performance are also provided for use together with the excess Ga growth method. Devices made with the method can be used for water purification, surface sterilization, communications, and data storage and retrieval.
