III-V semiconductors are a class of materials made from elements in groups III and V of the periodic table. Common examples include gallium arsenide (GaAs) and indium phosphide (InP). These semiconductors are known for their efficient electron mobility and direct bandgap properties, making them ideal for applications in optoelectronics, such as LEDs and solar cells. Due to their unique properties, III-V semiconductors are widely used in high-frequency and high-power devices, including transistors and laser diodes. They are essential in modern technology, particularly in telecommunications and computing, where performance and efficiency are critical.
