Properties of GaN

Gallium Nitride (GaN) is a semiconductor material that has been gaining popularity due to its unique properties. GaN has a wider bandgap energy than other semiconductor materials such as Silicon (Si) and Gallium Arsenide (GaAs). This means that GaN can operate at higher temperatures and voltages while maintaining its performance. GaN also has a higher electron mobility and thermal conductivity than other materials, making it an excellent choice for power electronics, LEDs, and RF amplifiers.

Bandgap energy

The bandgap energy of GaN is approximately 3.4 electron volts (eV), which is wider than Si and GaAs. This means that GaN can operate at higher voltages and temperatures without suffering from breakdown.

Electron mobility

GaN has a high electron mobility, which means that electrons can move through the material quickly. This results in faster switching speeds and higher efficiency in power electronics.

Thermal conductivity

GaN has a high thermal conductivity, which means that it can dissipate heat efficiently. This is important in high-power applications where heat can be a limiting factor.

Breakdown voltage

GaN has a high breakdown voltage, which means that it can withstand high voltages without suffering from breakdown. This is important in power electronics and RF amplifiers.

Applications of GaN

Power electronics

GaN has become a popular choice for power electronics due to its high efficiency, high switching speeds, and ability to operate at higher temperatures. GaN-based power electronics can be found in applications such as electric vehicles, solar inverters, and data centers.

Properties of GaN2

GaN2 is a derivative of GaN that has been developed to improve its performance in certain applications. GaN2 has a slightly wider bandgap energy than GaN, which means that it can operate at even higher voltages and temperatures. GaN2 also has a higher electron mobility and thermal conductivity than GaN, making it an even better choice for high-power and high-temperature applications.

Bandgap energy

The bandgap energy of GaN2 is approximately 3.6 eV, which is slightly wider than GaN. This makes GaN2 a better choice for applications that require higher voltages and temperatures.

Electron mobility

GaN2 has a higher electron mobility than GaN, which means that electrons can move through the material even faster. This results in even faster switching speeds and higher efficiency in power electronics.

Thermal conductivity

GaN2 has a higher thermal conductivity than GaN, which means that it can dissipate

heat even more efficiently. This is important in high-power applications where heat dissipation is critical.
