The enthusiasm for the research and development of two-dimensional semiconductor materials continues to rise, and national policies promote the acceleration of the development of the industry
Two-dimensional semiconductor materials refer to semiconductor materials with a thickness of only one or a few atomic layers. Compared with traditional semiconductor materials, two-dimensional semiconductor materials have the advantages of good scalability, strong quantum confinement effect, good stability, and good electrical properties, and are widely used in electronic devices, optoelectronic devices and other fields.
There are many types of two-dimensional semiconductor materials, including tungsten trioxide, black phosphorus, graphene, transition metal disulfide, bismuth telluride, silicene and antimonyne. Graphene is a two-dimensional semiconductor material composed of a single layer of carbon atoms, which has the advantages of strong electrothermal conductivity, good toughness, high mechanical strength and high electron mobility, and can be used to manufacture tympanic membrane electronic components, field-effect transistors and photodetectors. The graphene industry in mainland China started late, but the momentum of development is rapid, and local enterprises have obtained a number of related invention patents. In the future, with the acceleration of the development of the graphene industry, mainland two-dimensional semiconductor materials will gain broad market prospects.
In recent years, the state attaches great importance to the development of the two-dimensional semiconductor material industry, and has introduced a number of encouraging policies. In August 2023, the Ministry of Industry and Information Technology of the People's Republic of China and the State-owned Assets Supervision and Administration Commission of the People's Republic of China jointly issued the Notice on Printing and Distributing the Guiding Catalogue for the Key Development of the Industrialization of Frontier Materials (the First Batch), which clearly includes two-dimensional semiconductor materials, superconducting materials and metamaterials in the catalogue of frontier materials industries. In this context, the development speed of the mainland two-dimensional semiconductor materials industry will accelerate.
According to the "2024-2029 China 2D Semiconductor Materials Industry Market In-depth Research and Development Prospect Forecast Report" released by the Xinsijie Industry Research Center, 2D semiconductor materials, as new semiconductor materials, are widely used in electronic devices, optoelectronic devices and other fields. In the field of electronic devices, two-dimensional semiconductor materials can be used in the production of field-effect transistors and bipolar transistors, and in the field of optoelectronic devices, they can be used in the production of photoelectric sensors, photovoltaic cells, etc. In the future, with the deepening of research, the application range of 2D semiconductor materials will continue to expand.
The enthusiasm for the research and development of 2D semiconductor materials in mainland China continues to rise, and many new progress has been made. In March 2022, the team of associate professor Liu Bilu of Shenzhen International Graduate School of Tsinghua University successfully prepared β phase zirconium nitrogen chloride (β-ZrNCl) based on chemical vapor transfer method, which has excellent air stability and optoelectronic properties in two-dimensional form, and is expected to be used in high-performance electronic devices such as back-gate field-effect transistors in the future.
Industry analysts said that two-dimensional semiconductor materials have broad application prospects in the field of electronic devices and optoelectronic devices, and their application demand will further increase in the future as the development speed of the downstream industry accelerates. Benefiting from national policy support and technological progress, the prosperity of the mainland's two-dimensional semiconductor materials industry has been continuously improved. It is expected that in the future, with the continuous development of local enterprises, the development trend of the mainland two-dimensional semiconductor materials industry will continue to improve.
