The technical characteristics of the third generation semiconductor with gallium nitride as raw material make it possible to realize three times the charging power of the old silicon chip under the condition of halving the volume and weight.

Mobile phone charger is only one of the application scenarios of gallium nitride chip. According to public information, it has commercial applications in personal computers, data centers and other fields, and is expanding to solar energy, electric vehicles and other fields.

Reviewing the development history of the semiconductor industry, the changes of new technologies and new application scenarios will always have a profound impact on the industry pattern. When silicon changed from bipolar to MOSFET, many new power design companies were born.

Compared with silicon chips, gallium nitride chips have relatively less carbon dioxide emissions. According to statistics, by 2050, if more than 50% of silicon devices can be converted into gallium nitride devices, the global carbon emissions can be reduced by 10%.

Reducing the cost of gallium nitride devices, improving the industry ecology of gallium nitride and expanding new application scenarios will be difficult problems that must be solved. But these will not be achieved overnight. The popularization of gallium nitride chips will take time.
