The incorporation of GaN technology provides mobile devices with the capacity for rapid charging. BBK Electronics (OPPO Company) announced in September 2020 the full adoption of gallium nitride power ICs to enable the production of ultra-thin, 50-watt fast battery chargers. It is anticipated that the use of GaN components and integrated control solutions will reduce the charging time of mobile devices. Gallium nitride devices are utilised to manage ultra-high-frequency power solutions, thereby initiating a revolution in the power supply industry. The increasing use of gallium nitride semiconductors in radar design is anticipated to drive market expansion. In addition, GaN semiconductors are utilised in the construction of tactical radios for wideband communications on combat aircraft.
The rising demand for energy-efficient GaN devices and power semiconductors in wired communication is anticipated to drive market expansion. This growth is attributable to the expansion of the domain of telecommunications, as various internet service providers concentrate primarily on providing networks with higher capacity, ubiquitous connectivity, and lower latency using optical cable wires. Silicon carbide (SiC) and gallium nitride-based semiconductors are energy-efficient because they permit greater power efficiency at a reduced cost. Infineon Technologies produces silicon (Si), silicon carbide (SiC), and gallium nitride (GaN) for the development of light-emitting diodes (LEDs) and lightning arresters which provide external gap protection for power transformers.
The potential use of gallium nitride in the 5G infrastructure is also expected to contribute to the expansion of the market. In terms of traffic capacity, latency, energy efficiency, and data rates, 4G technologies will be replaced by 5G technologies. In 2021, it was anticipated that 5G technology would be commercially available. Numerous advantages would result, including a less expensive and more efficient communication network. Participating in the research and development (R&D) initiative to build 5G technology throughout the United States are telecom titans like AT&T and Nokia.
The Congressional Budget Office of the United States estimated that the federal budget deficit for the fiscal year (2020-2021) was USD 3.7 trillion and will exceed USD 2 trillion in the following fiscal year (2021-22) due to high spending on the COVID-19 recovery. It is calculated to reflect a long-term effect on the defence budget. The defence budget was reduced due to the federal budget deficit. Less demand for military radars, tactical radios, and software-defined radios will be a direct result of the reduction in the defence budget. It will alter the dynamics of this global industry further. In addition, the high development and maintenance costs associated with manufacturing gallium nitride components are a major factor that may impede the expansion of this market.
The growing use of technologically advanced GaN systems in the defence and aerospace industries is expected to stimulate market expansion. The expansion is a result of the increasing demand for increased bandwidth and performance reliability in radio communications, radars, and other applications. Due to its durability and tensile strength, SiC is an ideal material for the production of bullet-resistant jackets. GaN-based integrated circuits are utilised in radars for efficient navigation and real-time air traffic control. GaN can also offer higher operating frequencies for military jammers, terrestrial radios, and radar communication. Multiple global defence forces are anticipated to increase their use of wideband GaN power transistors, which will contribute to economic expansion.
The gallium nitride market share can be segmented on the basis of product, component, wafer size, region, end-users and competitors. The market is segmented by device type into Opto-semiconductor devices, power semiconductor devices, and RF semiconductor device segments. In 2019, the Opto-semiconductor device segment held the lion's share of the market for gallium nitride devices. This expansion can be attributed to the growing demand for Opto-semiconductor devices in solar cells, photodiode, laser, LED, and optoelectronics applications.

It has numerous advantageous properties, including high current amplification and low power consumption.
Based on wafer size, the market is segmented into 2-inch wafers, 4-inch wafers, and 6-inch and larger wafer categories. Combining esoteric compounds such as indium phosphide and graphene, the 2-inch size is comprised of these substances. It is primarily employed for military applications. During the period of analysis, the 4-inch wafer segment held the largest market share. This expansion can be attributed to the rising demand for optoelectronics devices, telecom frontends, high-power amplifiers, and high-temperature devices. Additionally, the adaptability of a 4-inch substrate for space communication applications is expected to accelerate expansion.
During the forecast period, the segment of wafers with a diameter of 6 inches or more significant is expected to record a higher CAGR. This growth is driven by the increasing use of this wafer in defence equipment due to its high breakdown voltage and low leakage current. The expanding use of this wafer in commercial applications, such as automotive collision-avoidance systems and wireless cellular base stations, would also contribute to expansion.
Based on component type, the market is segmented into the transistor, diode, rectifier, power IC, and other product types.
