As a new semiconductor material, cubic boron arsenide has good application prospects

Cubic boron arsenide is a new type of semiconductor material that has the advantages of high electron and hole mobility and high thermal conductivity. It is expected to be widely used in solar cells, chips and other fields in the future. In recent years, global enthusiasm for research and development of cubic boron arsenide has increased. With in-depth research and technological advancement, the development prospects of the cubic boron arsenide industry will continue to improve.

At the current stage of development, semiconductor materials have developed to the third generation. The third generation semiconductor refers to semiconductor materials with wide band gap characteristics such as gallium nitride (GaN), silicon carbide (SiC), diamond (C), aluminum nitride (AlN), and zinc oxide (ZnO). Silicon is an important semiconductor material with the advantages of low production cost and large resource reserves. However, its electron and hole migration speed cannot meet the production needs of high-performance semiconductor devices. Cubic boron arsenide overcomes the physical limitations of silicon and is expected to become the mainstream of the semiconductor material market in the future.

The main preparation method of cubic boron arsenide is vapor phase synthesis, which can be subdivided into chemical vapor deposition and chemical vapor transport. The chemical vapor deposition method has high operating costs and complicated operations. In 2018, American scientists used this method to successfully prepare cubic boron arsenide; the chemical vapor transport method is also called the chemical reaction assisted sublimation method. This method is suitable for small-scale laboratory production. The quality of the finished product is relatively poor. Limited by high technical barriers and other factors, the output and quality of cubic boron arsenide still need to be improved.

According to the “2023-2028 China Cubic Boron Arsenide Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center , cubic boron arsenide has good application prospects. In the field of solar cells, cubic boron arsenide has a thermal conductivity nearly 10 times that of silicon and can be used as an ideal material for high-efficiency solar cells in the future. In the chip field, cubic boron arsenide has the characteristics of high thermal conductivity and high carrier mobility, which can improve the computing speed of the chip. In recent years, the global high-end chip market as a whole has been in short supply. With the continuous breakthroughs in cubic boron arsenide production technology, it is expected to be widely used in the high-end chip field in the future.

At present, the cubic boron arsenide industry is in the early stages of development and has not yet achieved commercial application. Countries focus on laboratory research and development. my country and the United States are the first countries in the world to carry out cubic boron arsenide research. The main research institutions on cubic boron arsenide in my country include the National Nanoscience Center of the Chinese Academy of Sciences and the University of Electronic Science and Technology of China; the main research institutions on cubic boron arsenide in the United States include the University of California, Los Angeles, the University of Houston, and the Massachusetts Institute of Technology.

Industry analysts said that as a new semiconductor material, cubic boron arsenide has excellent performance and is expected to be widely used in the fields of solar cells and chips in the future. application. At present, the cubic boron arsenide industry is still in its infancy and has not yet achieved commercial application. In the future, with in-depth research and technology upgrades, the development speed of the cubic boron arsenide industry will further accelerate.
