New semiconductor technologies have great promise, silicon shot to its dominant position for a reason – chiefly the ease with which it can used. But other materials are always of interest due to their different potential properties. Now, Infineon Technologies is talking up the ‘game changing’ potential for gallium nitride (GaN) in AI and 5G applications, and it is worth checking in on the sector. A ’compound’ semiconductor is the combination of two or more elements. The most common compound semiconductor materials are gallium nitride (GaN), gallium arsenide (GaAs), indium phosphide (InP), silicon carbide (SiC), silicon germanium (SiGe), zinc sulphide (ZnS), and zinc selenide (ZnSe). GaN has shown promise in high-power and fast charging applications, in the mobile space, but…
