Wuhan overcomes the world's difficulties in detecting nanoscale thin-film materials

[China Packaging Network News] Wuhan succeeded in overcoming the world's problems in the detection of nano-scale thin-film materials. The "Hubei Engineering Laboratory for the Testing of Physical Properties of Functional Thin Film Materials" was established at Wuhan Future Technology City, a Wuhan-based laboratory. Jiayitong Technology Co., Ltd. and Huazhong University of Science and Technology jointly established.

With the development and application of new materials, nano-scale thin-film materials are widely used in many fields, and there are no internationally available devices that can directly detect the thermal properties of thin films. "One nanometer is only one of sixty thousandths of the diameter of one hair wire. How to detect the thermal properties of the film has become an international problem." Wang Yibing, general manager of Jiayitong, said that in the past, it was necessary to first deposit the film thickly and then treat it. The destructive test can only be performed after the film material is scraped off to form a certain quality powder.

After many years of technical hard work, Huazhong University of Science and Technology "Cheung Kong Scholars" Prof. Xiang Shui team led the team to develop China's first optical power thermal analyzer to detect film thickness up to 5 nm. According to reports, the optical power thermal analyzer is a laser irradiation on the surface of the nano-film material, and the phase transition temperature point and the thermal expansion coefficient of the film are detected by the reflected light power. This scientific and technological achievement was successfully transformed in Jiayitong and it became industrialized.

As the first research base for functional properties of functional thin film materials in China, after the establishment of a provincial engineering laboratory, 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, and thin films will be implemented.

“Thin film materials are disruptive technologies for global scientific and technological progress. As thin-film technologies become thinner and thinner, subversive test equipment is needed.” Pan Feng, a professor at Tsinghua University and leader of the national key research and development plan expert group, told the Changjiang Daily reporter that technology The Ministry of Science and Technology has set up a major special research and development project for the genome of materials. One of the important tasks is to overcome high-throughput characterization and detection technologies. Hubei can rely on the leading edge of thin film detection and R&D to make greater scientific contributions.
