LED performance breakthrough! "Zero defect" new semiconductor material

The day before President Li Sicen from the front, served as a multinational team of researchers NTU professor He Zhihao electronic components, successfully developed a new semiconductor material known as "zero defect", is expected to significantly enhance the luminous efficiency of LED.

This team is composed of the United States of California Berkeley university professor AliJavey, King Abdullah University of science and Technology (KAUST), Professor He Zhihao, the president of Li Sicen et al, has published a paper, CO first author of the paper even dexuan is the Department of electrical engineering doctoral, 2015 has just completed his PhD interview, also get the international society of electronic semiconductor IEEE awarded the scholarship, will graduate in this study.

National Taiwan University multinational research team pointed out that in the past, the thinner the semiconductor material, its own physical defects will be available for electronic, optoelectronic components, a negative impact. At present, the research team found a simple method to repair the defect, construct a single two-dimensional semiconductor material MoS2 of high quality, no past two-dimensional material defect density problems, hope that the future can enhance the LED luminous efficiency, more then have the opportunity to become one of the important material selection in the small ultra conductor element.

According to the research team said, this kind of material can be developed with high performance transparent, flexible LED display, and the ultra efficient solar power components, and the high sensitivity of the optical detection element, and lower power consumption of nano semiconductor transistor.

LEDinside to review their papers and published content, the research team is the molybdenum disulfide (MoS2) imide (bistriflimide) material infiltration in organic acid, thus can greatly improve the quantum efficiency of the two-dimensional material, enhance the limit, the increase of less than 1% from the original effect, increased to nearly 100%, in other words, nearly multiplier effect, so some media reports say the LED luminous efficiency can be increased by 100 times, this is the description of the error, and not really.

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