Gallium nitride (GaN) is a binary III/V semiconductor widely considered to be a promising alternative to silicon. It possesses a wider bandgap than silicon, allowing it to withstand higher voltages in electronic devices. 1
Higher voltages enable GaN components to be smaller and more energy-efficient than silicon. In addition, GaN outperforms silicon during operation at elevated temperatures, helping to overcome current design limitations imposed by silicon technology in complex or challenging settings such as automobile electronics. 2
