The semiconductor material is receiving much attention
Presently, third-generation compound semiconductors (SiC and Galium Nitride) are being more widely studied. These devices will be able to replace silicon in the future, as they play the same role as traditional silicon. The future of automotive, 5G, and the Internet of Things will offer many development opportunities.
But silicon carbide or gallium oxide aren’t the final point. Gallium oxide (Ga2O3) recently made headlines again, thanks to its greater band gap that silicon carbide or gallium nitride. This compound semiconductor can be used for higher power applications. These compounds have unique strengths. Research on gallium dioxide has returned to the forefront of research in recent decades.
Although gallium oxide has been around for a long time, research institutes and companies conducted extensive research into it. In terms of practical applications it’s not as popular as gallium carbide and galium nitride. As the application requirements are improved, performance requirements for high power devices have increased. Because of this, people now see the benefits and potential of gallium oxide and their research and development has increased. The United States, Japan. Germany and other countries have adopted it. Competition focus and research focus.
Gallium oxide MOSFET
Earlier this summer, Dr. UttamSingisetti, an associate professor of electric engineering at the Faculty of Engineering Applied Sciences at University of Buffalo and his students made a 5-micron-thick MOSFET out of gallium oxide.
According to the researchers, the breakdown voltage of the transistor is 1850V. That is nearly twice that of gallium-oxide semiconductors. A material’s ability to conduct electricity is called the breakdown voltage. A device’s ability to handle more power is determined by its breakdown voltage.
Because of its large size, the transistor isn’t suitable for small-sized devices like smart-phones. However, it could help to control the flow of energy in large-scale operations like power plants that harness solar and wind energies, electric cars, trains and aircrafts. Its low thermal conductivity means that further research is needed.
Researchers from the University of Florida as well as the US Naval Research Laboratory have been studying Gallium dioxide MOSFET. Stephen Pearton from the University of Florida is an engineer and professor of materials science. He said that the University of Florida is studying the possibility of developing gallium oxide MOSFETs. These miniature electronic switches were traditionally made out of silicon. They are commonly used in laptop computers, smart phones, and other electronic products.
System like electric vehicle charging stations need to work at higher power levels than the silicon-based ones. This is where gallium oxide MOSFETs might be the best solution. This team discovered that the MOSFETs needed to be more effective in releasing heat.
