China News Service, Harbin, June 12 (Reporter Shi Yifu) In the past two days, the gem-encrusted Harbin Institute of Technology admission notice has become a hot topic and has become a hot search. Sina Weibo has been read 260 million times.
On the 12th, a reporter from Chinanews.com revealed the hard-core technology behind the admission letter of Harbin Institute of Technology.
The diamonds and sapphires set in the admission letter of Harbin Institute of Technology were independently developed by the infrared thin film and crystal team of the Institute of Composite Materials and Structures of the university.

According to Professor Zhu Jiaqi, the team leader, the diamonds we are familiar with belong to gem-grade diamonds and natural diamonds, while the diamonds set in the notice belong to industrial diamonds, which are used in the heat dissipation of high-power devices and the development of quantum chips that cannot meet extreme requirements. The diamond single crystal with performance requirements has been engraved with high-energy pulsed ultraviolet laser patterns developed by the team, turning "waste" into treasure.
"I hope to stimulate the scientific research interest of the majority of freshmen, and demonstrate the hard core strength and mission of our school in the research and application of new materials."

Diamond single crystal is widely used in quantum communication extreme optics, artificial intelligence, ultra-precision machining and other fields. At the same time, as an ideal heat dissipation material for high-power devices and chips, the research on related technologies has become a key technical problem that needs to be broken through in my country.
Harbin Institute of Technology's infrared thin film and crystal team has long been committed to the preparation and application of large-scale and high-quality diamond materials in China, and has achieved the independence of China's inch-scale diamond production equipment.

According to Mr. Yao Tai from Harbin Institute of Technology, the sapphire set in the notice is prepared in the laboratory. The sapphire single crystal has excellent optomechanical, chemical and electrical properties, and is internationally recognized as the preferred material for optoelectronic windows.
