Gallium nitride (GaN) is a semiconductor material made from gallium and nitrogen. It is known for its wide bandgap, which allows it to operate at higher voltages and temperatures compared to traditional semiconductors like silicon. This property makes GaN ideal for applications in power electronics, such as LEDs and power amplifiers. In addition to its use in lighting, gallium nitride is increasingly used in 5G technology and electric vehicles due to its efficiency and compact size. Its ability to handle high frequencies and power levels makes it a key material in modern electronic devices, contributing to faster and more efficient performance.
