Twenty-seven-year-old master student Xiao Zigang of National Taiwan University spent more than a year trying to put more than one hundred ultra-fine “矽锗 nanowires†on the measuring device. He also cooperated with the National Taiwan University’s local research team to confirm the wave-type for the first time. The heat transfer phenomenon rewrites the basic hypothesis that university physics textbooks believe that heat will spread. Zhang Zhiwei, an assistant professor at the National Taiwan University of Density and an assistant professor at the National Taiwan University of Solidarity, explained that in the course of heat conduction, numerous molecular collisions occur. This theorem has been taken for granted since the industrial revolution. Therefore, the traditional heat conduction phenomenon defined in textbooks has long been known. Just like “put creamer into coffeeâ€, the creamers will collide with each other and gradually spread, but it will destroy the fluctuating nature of the heat conduction itself, and cause the heat energy to not transmit information like electronic or optical fiber. In the past, it was necessary to observe the fluctuating nature of heat conduction. They must all be at a very low temperature of 270 degrees Celsius. However, the NTU research team broke through the predicament and found that at room temperature, heat energy passes through only 10,000 times of hair. When nanowires are used, the fluctuating heat conduction phenomenon can be maintained at eight micrometers in length, which is almost a lossless, collision-free wave phenomenon. This finding rewrites the basic assumption that thermal divergence is considered in university physics textbooks. The new study was published in the international top journal Natural Nanotechnology. Zhang Zhiwei emphasized that most of the energy is converted from heat to electricity. New discoveries can make waste heat from thermoelectric elements more efficient when converted into electricity. The potential for the future will be unlimited. If continuous research and development is applied to the electronics industry, there will be opportunities for mobile phones. The notebook is more heat-resistant. The behind-the-scenes hero of this study is Xiao Zigang, who was only 27 years old and graduated from the Institute of Applied Physics at National Taiwan University. He spent more than 400 days in the laboratory. Using robotic arms and electron microscopes, he used hundreds of "矽锗 nanowires" to use fishing-like methods to "fish" on measuring devices. It usually takes one afternoon. It may take two to three days before it can detect heat conduction. Due to the high failure rate, the test is patient, careful, and persevering. The research team affirmed his research contribution. At the time of publishing the paper, his name was hung in front of senior scholars from National Taiwan University, and the new president of National Taiwan University Yang Lanchi praised him: “The performance of a graduate student at National Taiwan University is brighter than that of doctoral students at world-class universities. eye!" Xiao Zigang said that this research is the common effort of the NTU's local research team and is pleased to participate in this study and use it as a master's thesis. He said that he has obtained a full-year scholarship for four years, about NT$1.5 million each year, and will soon go to Cambridge University in the United Kingdom to pursue his doctoral degree.
