As a new quantum material, stanene industry has good development prospects

Stanene, also known as a single layer of tin atoms, has a two-dimensional honeycomb structure similar to graphene and is a new type of quantum material. The crystal structure of stanene is based on α-tin with a diamond structure. Since it does not have a layered structure, it cannot be produced by mechanical exfoliation, so the technical barriers to production are extremely high. Compared with two-dimensional materials such as graphene, silicon-tin, and germanene, tinene has longer bond length and better electrical conductivity. It is expected to become the world’s first super material with a conductivity of 100.0% at room temperature.

According to the “2022 Global Stanene Industry Market Status Research Report released by the Industrial Research Center, the preparation method of stanene is mainly molecular The beam epitaxy method requires placing the stanene raw material in an ultra-high vacuum chamber and using methods such as glow discharge ionization, high-temperature evaporation, and electron beam heating evaporation to generate a molecular beam, and finally generate a single layer on the precious metal substrate. Stanene. In 2015, my country realized for the first time the use of molecular beam epitaxy growth technology to prepare a two-dimensional crystal film of stanene. In 2018, molecular beam epitaxy technology was able to successfully prepare a single-layer stanene with a stretched lattice structure. At present, the molecular beam epitaxy method has become tin Main flow preparation method of ene.

Stanene has the advantages of dissipative conductivity and topological superconductivity at room temperature. It can realize electron transport without energy loss at room temperature. Highly integrated electronic devices are expected to become the main application field of stanene. According to statistics from the China Semiconductor Industry Association, my country’s integrated circuit industry sales in 2021 will be 1.04583 billion yuan, a year-on-year increase of 18.2%. Stanene can completely replace silicon in circuit board transistors. As my country’s integrated circuit technology continues to upgrade, the requirements for integration in its application fields will continue to increase. Stanene will have broad development prospects as a new material. At the same time, stanene can also be widely used in the new generation of quantum computers by virtue of stable electron pairing and quantum coherence effects in the superconducting state.

At present, stanene is in the laboratory research and development stage, and the industry has not yet achieved commercial development. Tsinghua University, Shanghai Jiao Tong University, SLAC National Accelerator Laboratory under the U.S. Department of Energy and Stanford University are the main research institutions for stanene. In 2022, Jia Jinfeng’s experimental team at the School of Physics and Astronomy at Shanghai Jiao Tong University cooperated with the research groups of Zhang Zhenyu and Cui Ping at the University of Science and Technology of China. Based on molecular beam epitaxy technology, the coexistence of stanene topological edge states and superconductivity was achieved, providing a solution for multi-layer tin This lays the foundation for constructing one-dimensional topological superconductivity in the ene system.

Industry analysts said that as a new two-dimensional material, stanene has broad application prospects. With the continuous innovation and breakthrough of research and development technology, stanene The scope of application will be expanded, and the industry is expected to achieve commercial development. The stanene industry has high technical barriers. In recent years, many scientific research teams in my country have worked hard to make new progress in the research of stanene materials, which has a positive impact on the development of the industry.
