Gallium oxide (Ga2O3) is the fourth generation semiconductor material with huge future market development potential.

Gallium oxide (Ga2O3), also known as gallium trioxide, is a white metal that is slightly soluble in hot acid/alkali solutions and easily soluble in alkali metal solutions or dilute inorganic acids. Gallium oxide has five isomers: α, β, γ, δ, and ε. As a new ultra-wide bandgap semiconductor material, gallium oxide has excellent conductivity, optics, thermal stability, and high voltage resistance. As well as wide bandgap characteristics, it can be used to manufacture miniaturized, high-power electronic components.

As one of the fourth-generation semiconductor materials, gallium oxide has broad application prospects in semiconductor, industry, high voltage, consumer electronics, telecommunications, automobiles, electrical equipment and other fields. Power devices made of gallium oxide are superior to products made of silicon carbide and gallium nitride in terms of performance, cost, and application range. In the next ten years, as demand escalates, gallium oxide is expected to gradually replace carbon and nitride. Gallium and other third-generation semiconductor materials.

Attracted by the broad market prospects, companies around the world are actively developing the gallium oxide market, among which companies in Japan and the United States are leading the way in gallium oxide research and application. Gallium oxide is a must for domestic and foreign science and technology strategies. In the international market, companies or institutions engaged in the research and development and production of gallium oxide include Japan’s Flosfia, Japan’s Novell Crystal Technology, the U.S. Air Force Research Laboratory, the U.S. Naval Laboratory, and Germany’s Leibny Ci Crystal Growth Research Institute, Saint-Gobain, France, etc.

According to the “2023-2027 Gallium Oxide Industry In-depth Market Research and Investment Strategy Suggestions Report released by the Industrial Research Center, currently my country There are still few companies engaged in gallium oxide research and development, and among them, less than 10 A-share companies are involved in this business, mainly including Lanxiao Technology, Nanda Optoelectronics, AVIC Electromechanical, Sanan Optoelectronics, China Ceramics Electronics, Xinhu Zhongbao, etc. In terms of gallium oxide R&D institutions, the main ones include China Electronics Technology Institute 46, Shanghai Institute of Optics and Mechanics, Shanghai Institute of Microsystems, Zhejiang University Hangzhou Science and Technology Innovation Center, Xi’an University of Electronic Science and Technology, etc.

In recent years, my country’s attention to gallium oxide has also been increasing. In 2017, gallium oxide was included in the key research and development plan. In 2018, the Beijing Municipal Science and Technology Commission listed gallium oxide as a key new material project. In 2022, the Ministry of Science and Technology listed gallium oxide as a key new material project. Gallium is included in the “14th Five-Year Plan Key R&D Plan”. The preparation methods of gallium oxide include liquid phase guided mode method, gallium ammonium sulfate method, three-stage electrolysis method, hydration method, microwave hydrothermal method, etc. my country’s research on gallium oxide has a history of more than ten years, but due to technical difficulties and high production costs , currently gallium oxide is still in the research and development stage and is still far away from large-scale production and application.

Industry analysts said that gallium oxide is a fourth-generation semiconductor material that has good performance, low loss and high power density in the market. Against the background of the continuous release of demand for power devices, the gallium oxide market has huge development potential. As a strategic high ground for science and technology, the number of domestic and foreign companies and institutions engaged in research on gallium oxide is constantly increasing. In the future, with technological breakthroughs and in-depth research, the industrialization process of gallium oxide will be accelerated, and the application scenarios are also expected to be further expanded.
