(Central News Agency reporter Chen Chih-chung, Taipei, 24th) A cross-university research team composed of National Central University (NCU) and National Tsing Hua University (NTHU) has successfully advanced cutting-edge materials research by precisely simulating the numerical process of laser manufacturing to analyze the transient heat transfer mechanism. Their findings were recently published in the international top-tier journal Advanced Functional Materials.
National Central University today issued a press release introducing the latest research achievements of the cross-university team, including Professor Hong Wei-hsuan from the Institute of Materials Science and Engineering at NCU and Professor Que Yu-lun from the Department of Materials Science and Engineering at NTHU.
This research focuses on the field of advanced materials, particularly in laser processing, which is a core technology for material modification and nanostructure fabrication due to its high precision and rapid processing characteristics.
However, the team pointed out that during the extremely short moment of laser interaction, the material surface undergoes drastic temperature fluctuations. This instantaneous high temperature and heat transfer behavior are difficult to directly observe through existing physical experimental equipment, posing a major challenge to understanding material reaction mechanisms and optimizing manufacturing processes.
To overcome these limitations, NCU team member Hsu Tsai-chen first established a precise numerical model for the laser processing process, utilizing multi-physics field simulation technology to accurately analyze the temperature distribution and dynamic heat transfer behavior under laser irradiation. The NTHU team, on the experimental side, achieved laser-induced precursor conversion and low-temperature transfer of two-dimensional materials.
The research team analyzed the heat-affected zone of materials at the microsecond level by changing the laser power, scanning speed, and operating conditions in the simulation. During the paper review, committee members questioned the laser-induced temperature mechanism and physical changes. The team provided convincing theoretical evidence through simulation data, demonstrating the important value of mutual verification between simulation and experiment.
Through this simulation technology, physical mechanisms that are difficult to reach by experiments can be complemented, which has a profound impact on precisely controlling material properties. It is expected to be used in laser process optimization and high-performance material design in the future.
The research team also plans to extend the simulation framework to the development of semiconductor heterogeneous integration and energy-saving sensing components, strengthening Taiwan's international competitiveness in the field of high-performance electronic materials.
