According to reports, US researchers have developed a new type of GaN based electronic device called resonant tunneling diode, which has been applied to 5G technology with a peak speed higher than expected.

"The frequency and output power of GaN based resonant tunneling diodes are higher than that of traditional materials, and the key to their speed is the use of Gan materials," the researchers said.

The GaN based "resonant tunneling diode" breaks the record of current output and switching rate of traditional devices, and enables applications (including communication, networking and remote sensing) to obtain electromagnetic waves and terahertz frequencies in the millimeter wave range.

As the third generation semiconductor material, gallium nitride (GAN) is a kind of hard material with high melting point (melting point is about 1700 ℃), which has the characteristics of high frequency, high efficiency, high pressure resistance and so on. It is used to make a variety of power devices and chips.

Gallium nitride has been studied in the field of semiconductor materials for many years. Recently, it is widely known because it can be used in chargers. The charging market is not the only place where Gan power devices can be used, but also in the fields of Optoelectronics and RF.

It is worth mentioning that, in the RF field, gallium nitride RF devices are suitable for high-frequency and high-power scenarios, and are excellent products in the 5G era. They will replace Si based chips and be used in 5G base stations, satellite communications, military radars and other scenarios.

In the Political Bureau meeting, the construction of 5G base station ushered in the peak, the corresponding number and quality of various RF devices and chips are improving, and the market demand is strong. Gallium nitride technology is gradually occupying the market, which is unstoppable.

According to the prediction of topu Industry Research Institute, by 2023, the base station Gan RF device scale will reach the peak, reaching 11.26 billion yuan. Combined with the market of satellite communication and military radar, it is predicted that the Gan RF market will grow from 645 million dollars in 2018 to about 2 billion dollars in 2024.

In addition, GaN based UV laser has important application value in UV curing, UV sterilization and other fields. At present, both China and the United States have used GaN based UV disinfection and sterilization, and the relevant market has grown.

2019 is a year of rapid changes, the economy is under downward pressure, and trade war conflicts have intensified, and many industries have entered a recession cycle. However, semiconductor industry 2019 is a year of rapid changes. The recession cycle has entered, but the semiconductor industry continues to move forward on the opportunity of domestic substitution and industrial renewal. For compound semiconductors, whether it is gallium nitride for radio frequency or silicon carbide for power electronics, there has been considerable development.

The 5G communication business is entering a period of rapid expansion, and the corresponding GaN chips and power chips continue to grow. Gallium nitride technology has basically determined its technical route and application in the field of radio frequency, that is, growing gallium nitride epitaxy on silicon carbide high-purity insulating substrates, and making chips on it for communication applications such as high-frequency power amplifiers.

With the development of 5G communications and the Internet of Things, the demand in this field will be increasing. It is worth noting that the application of GaN technology in power supplies. The cost and performance of gallium nitride power devices grown on silicon substrates have been much better than similar silicon devices. Although its long-term reliability still needs to be verified, for consumer-grade applications such as mobile phone fast charging, GaN is expected to be fully introduced and applied.

Silicon carbide is a very promising material, especially in power devices and power applications. It is currently receiving great attention. With the delivery of the first batch of domestic Tesla electric vehicles by the end of 2019, silicon carbide power devices related fields have been fully replaced. The trend of silicon-based IGBTs is becoming more and more obvious. Especially the high efficiency, low weight, small volume, and ease of use in heat dissipation and parallel connection brought by silicon carbide are crucial to the overall design of new energy vehicles.

The rapid development of industries such as automotive electronics, 5G technology, new energy vehicles, and rail transportation has increased the demand for high-temperature, high-power, high-voltage, and high-frequency devices in electronic technology, so the third generation of semiconductors came into being. The third generation semiconductors mainly include silicon carbide (SiC), aluminum nitride (AlN), gallium nitride (GaN), diamond, and zinc oxide (ZnO). Among them, the more mature ones are SiC and GaN.
