LED performance breakthrough! "Zero Defect" new semiconductor material was born

Recently, a multinational research team consisting of Li Wei, the president of the front desk, and He Zhihao, a professor at the National Taiwan University of Electronics, has successfully developed a new semiconductor material called “zero defect”, which is expected to greatly improve the LED luminous efficiency.

The team consists of AliJavey, a professor at the University of California, Berkeley, He Zhihao, a professor at King Abdullah University of Science and Technology (KAUST), and Li Wei, the president of the front desk. He has published a paper, and the first author of the paper, Lian Dexuan He is a Ph.D. in the Department of Electrical Engineering of National Taiwan University. He has just completed a doctoral oral exam in 2015 and received a scholarship from the International Institute of Electronics and Semiconductors in IEEE. He will graduate from this program.

The multinational research team of National Taiwan University pointed out that the thinner the semiconductor materials in the past, the physical defects of their own will have a negative impact on the usable performance of electronic and optoelectronic components. At present, the research team has found a simple method to repair defects, and constructed a high-quality single-layer two-dimensional semiconductor material MoS2. There is no problem of high defect density of the two-dimensional materials in the past, and it is expected that the efficiency of LED illumination can be improved in the future, and later Opportunity is one of the important material choices in ultra-small semiconductor components.

According to the research team, this material can develop a transparent, flexible high-performance LED display, as well as ultra-efficient solar power components, as well as high-sensitivity light-detecting components, as well as lower power consumption. Nano-scale semiconductor transistor components.

The LED network examines their papers and published content. The research team infiltrates the molybdenum disulfide (MoS2) material into the organic super acid of the bistriflimide, which can greatly improve the quantum efficiency and the limit of the two-dimensional material. From the original increase of less than 1%, the effect increased to nearly 100%, in other words, the effect of nearly multiplying, so some media reported that LED luminous efficiency can be increased by 100 times, this is a wrong description, not true.

This material is to be commercialized, and it is expected that there will be a period of time before the world can wait and see that it is better to have better optoelectronic and semiconductor materials for the benefit of the people and industry.
