Two main factors are responsible for the growth of the electronics market: the automation and digitization of the industry as well as the increasing awareness of ecological responsibility and sustainable processes. Energy consumption can only be reduced if electronic systems can become more energy and resource efficient.
So far, silicon has dominated the electronics industry. In addition to its low cost and almost perfect crystal structure, silicon is also a particularly successful semiconductor material because its band gap enables good charge carrier concentration and speed as well as good dielectric strength. However, silicon electronics is gradually reaching its physical limits, especially with regard to the required power density of future generations of components and the resulting compactness of the devices equipped with them.
The use of the semiconductor gallium nitride (GaN) in power electronics has already overcome the limitations of silicon technology. GaN has the ability to exhibit greater performance than silicon at very high voltages, temperatures and switching frequencies, thus enabling significantly higher energy efficiency. In numerous energy-intensive applications, this means a significant reduction in energy consumption.
