Recently, a research team from the University of Hong Kong has made a major breakthrough in the field of diamond and successfully developed a revolutionary diamond peeling technology. The publication of this result not only demonstrates the strength of the University of Hong Kong in materials science research, but also opens up new possibilities for the application of diamond.
As the hardest material in nature, diamond has long been considered the "Everest" of electronic and photonic materials. However, it is a very challenging task to successfully peel off high-quality large-area diamond films. The person in charge of the project, Associate Professor Chu Zhiqin, and his team spent five years and finally produced an ultra-thin and flexible diamond film, which attracted widespread attention.
Talking about the background of this research, Chu Zhiqin first proposed the idea of preparing a large-area flat diamond film in 2019. At first, scientific research progressed slowly, and it even faced the crisis of giving up because there were no significant results for two years. The turnover and setbacks of team members make the future of the project full of uncertainty. However, Chu Zhiqin always firmly believes that this research has huge application potential. In the end, doctoral student Jing Jixiang's flash of inspiration brought about a turning point. Through a series of experiments, he discovered a successful method for peeling off the film after destroying the diamond edge.
By continuously adjusting the mechanical parameters, the research team was able to obtain a large complete diamond film from the corners of the diamond. The actual size of the film was larger than expected, reaching more than 4 inches. What’s even more amazing is that this diamond film is not only as thin as paper, but also has good flexibility and plasticity, and can control its properties through mechanical deformation.
The research results of Chu Zhiqin's team are not only of great significance in terms of physical methods, but also open up a new path for the development of diamond semiconductor materials. Traditionally, the process of preparing diamond semiconductor materials is complex and difficult, but this technology can achieve performance control through simple physical means and has potential for wide application prospects. The research results were recently published in the top international academic journal "Nature", once again confirming the leading position of the University of Hong Kong in cutting-edge scientific research.
In the process of publishing scientific research results, the team has experienced many setbacks. Initially, they submitted their paper to Science, but it was rejected due to differences in review opinions. Later, when they submitted it to Nature, they encountered a situation where it was not submitted for review. After several months of supplementary experiments and data, the paper was finally published successfully after rigorous review. This process not only tested the patience and perseverance of the scientific research team, but also reflected their unremitting pursuit of scientific exploration.
Chu Zhiqin mentioned in the interview that scientific research requires a spirit of perseverance and a correct attitude towards failure. The scientific research concept he upholds emphasizes never giving up in the face of difficulties. It is this concept that promotes the team's success. He believes that although scientific research is full of challenges, only by maintaining a love for science can we continue to innovate and achieve breakthroughs in difficult explorations.
The publication of this research laid the foundation for the practical application of diamond materials in the future. In many fields such as electronics, photonics, and machinery, the excellent performance of diamond films will undoubtedly bring new development opportunities to related industries. The success of Chu Zhiqin's team is not only an honor for the individual and the team, but also an encouragement to the entire scientific research community, inspiring more scientific researchers to meet challenges and persist in exploration.
In today's era of rapid technological development, this breakthrough result has drawn more attention to the cutting-edge development of materials science and its application potential in future life. The technological innovation of diamond films will also trigger broader discussions, promote the deep integration of scientific research and industry, and inject new impetus into scientific and technological progress and economic development.
