Wuhan in conquering the world's problems of nanoscale thin film material testing again fruitful - 'Physical properties of functional thin film material testing technology engineering laboratory in Hubei Province' was set up in Wuhan Future Science and Technology City, the laboratory by Wuhan Jia Yi Tong Technology Co., Ltd. And Huazhong University of Science and jointly set up.
With the development and application of new materials, nano-scale thin film materials are widely used in many fields, but there is no device in the world that can directly detect the thermal characteristics of the thin film. '1 nanometer is only 1/600 of the diameter of a hair wire , How to detect the thermal properties of the film has become an international problem. "Wang Yibing, general manager of Jia Yi Tong said that in the past the film needs to be deposited very thick, then the film material to be scraped off to form a certain quality of the powder before it can be destroyed Sexual testing.
After many years of technological tackling, Huazhong University of Science and Technology Yangtze River scholar Professor Miao Xiangshui team led the research and development of China's first optical power thermal analyzer, testing film thickness up to 5 nm. According to reports, optical power thermal analyzer is the laser Irradiated to the surface of the nanometer film material, the phase transition temperature and the coefficient of thermal expansion of the film were measured by the reflected optical power, and the scientific and technological achievements were successfully transformed in Jiayi Tong and industrialized.
As the first research base of physical property testing technology for functional thin film material in China, the provincial engineering laboratory will be set up to conduct the thermal analysis of thin film materials, sample preparation and processing of thin film materials, electromagnetic analysis of thin film materials, mechanical analysis of thin film materials, Materials Optical Analysis 5 vertical research laboratories.
'Thin film material is a disruptive technology for global scientific and technological progress. As thin film technology becomes thinner and needs disruptive testing equipment,' Professor Pan Feng, a professor at Tsinghua University and leader of a national key R & D program, told the Yangtze River Daily Newspaper that technology Ministry has set up a major research and development of the material genome special, one of the important tasks is to overcome the high-throughput characterization detection technology, Hubei can rely on the film detection R & D leading edge, to make greater contributions to science.
