Gallium nitride (GaN) offers fundamental advantages over silicon. In particular, the higher critical electrical field makes it very attractive for power semiconductor devices with outstanding specific dynamic on-state resistance and smaller capacitances compared to silicon MOSFETs, which makes GaN HEMTs great for high speed switching.
Galliumnitrid – Wikipedia
Galliumnitrid (GaN) ist ein aus Gallium und Stickstoff bestehender III-V-Halbleiter mit großem Bandabstand (wide bandgap), der in der Optoelektronik insbesondere für blaue und grüne Leuchtdioden (LED) und als Legierungsbestandteil bei High-electron-mobility-Transistoren (HEMT), eine Bauform eines Sperrschicht-Feldeffekttransistors (JFET), Verwendung findet.

Rein technisch gesehen hat GaN auf SiC die Nase vorn. Im Vergleich zu Si sind die SiC Substratkosten jedoch deutlich höher (ca. 1000 USD pro 4" Wafer). Gegenwärtig sind GaN-Transistoren bereits von asiatischen und amerikanischen Firmen kommerziell erhältlich. In Deutschland wird an verschiedenen Instituten und Firmen mit Hochdruck an der Entwicklung von AlGaN/GaN-Transistoren gearbeitet ...

The Worlds Best Gallium Nitride_News_SiC …
Gallium nitride devices today are often built on substrates of sapphire, silicon carbide, or even plain silicon. But in each of those materials, the atoms in the crystalline lattice are spaced differently from those of gallium nitride, introducing a strain of the sort you’d get if you tried to stack goose eggs on top of a layer of chicken eggs. What you really want is a substrate sliced out ...

SiC and GaN are called “Wide Bandgap Semiconductors” (WBG), due to the energy needed to blow up the electrons of these materials from the valence band to the conduction band: while in the case of silicon this energy is 1.1eV, it is about 3.2eV for the SiC (Silicon Carbide), and 3.4eV for GaN (Gallium Nitride). This results in a higher applicable breakdown voltage, which can reach 1200 ...
