          Shenzhen Risen OPTO Co.,Ltd,led flood light supplier,Aluminum Alloy Flood Light Manufacturers,waterproof led lamps supplier china .Recently by the front desk president Li sicen, former president of the NTU electronic Professor Zhi Hao he composed of multinational team of researchers, successfully developed, known as the "zero defect" new semiconductor material, is expected to dramatically increase LED luminous efficiency.
          The composition of the team is the University of California, Berkeley professor AliJavey, Abdullah king of University of science and Technology (kaust) Professor Zhi Hao he, and in front of the chancellor Li sicen et al. Have published papers, the common first author even de Xuan is a National Taiwan University Department of electrical engineering, a PhD, 2015 has just completed the Dr. interview, also get international electronic semiconductor IEEE awarded the scholarship, will graduate in this study.
         NTU International Research Team pointed out that past semiconductor material if the thinner, its physical defects will be for electronic and optoelectronic device available efficiency, resulting in negative effects. And the the research team found defect repair method is simple, to construct the quality of single two-dimensional semiconductor material MoS2, no past two-dimensional defect density is too high problem, look forward to the future and improve the efficiency of the LED light, then have the opportunity to become one of the important materials of ultra small semi conductor element options.
According to the research team said, this material can develop transparent, and has flexible high performance LED display, and super efficient solar power components, and high sensitivity detection of light elements, and lower power consumption of the nano semiconductor transistor element.
          Ledinside view their papers and published content, the research team is the infiltration of MoS2 materials in imine (bistriflimide) organic Superacid inside, as a result can be a substantial increase in two-dimensional quantum efficiency, enhance the limit, from originally the increase of less than 1% of the effect, increased to nearly 100%, in other words, nearly doubling the effect, so some of the media reports said LED luminous efficiency can be up to 100 times. This is described by the error, is not true.
         This material is to be commercialized, it is expected that there will be some time, the world can be seen, expected to have a better photoelectric and semiconductor materials for the benefit of the population and industry.
