Silicon carbide (SiC) is another alternative to silicon, but a GaN generally has more attractive fundamental material properties. Current GaN devices are made on hybrid substrates: thin layers of GaN on silicon or silicon carbide creating GaN-on-Si or GaN-on-SiC HEMT (high electron mobility transistor) structures (Figure 3).

Silicon carbide has excellent thermal, mechanical, chemical and electrical properties. It is not only one of the best materials for making high temperature, high frequency, high power electronic devices, but also can be used as the substrate material based on GaN
TLDR: it depends on the appliion. The previous answers are pretty much on the money. Gallium nitride (GaN) is unlikely to replace silicon as the fundamental building block of transistors or ultra large scale integrations (ULSIs) because of the
Silicon carbide (SiC) is another alternative to silicon, but GaN generally has more attractive fundamental material properties. Current GaN devices are made on hybrid substrates: thin layers of GaN on silicon or silicon carbide, creating GaN-on-Si or GaN-on-SiC high-electron-mobility transistor (HEMT) structures ( Figure 3 ).
Silicon Carbide based devices have been used for short wavelength opto-electronic, high temperature, radiation resistant appliions. The high-power and high-frequency electronic devices made with SiC are superior to Si and GaAs based devices.
However, silicon carbide exhibits excellent thermal resistance (meaning it can move more heat in a given time) and far fewer losses (meaning it can operate at higher temperatures). To determine how much power a SiC device can dissipate, we use a graph like the one shown on the right side of Figure 4, which gives the power density (W/mm2) for different types of devices.

Silicon carbide (SiC) has excellent properties as a semiconductor material, especially for power conversion and control. However, SiC is extremely rare in the natural environment. As a material, it was first discovered in tiny amounts in meteorites, which is why it is also called “semiconductor material that has experienced 4.6 billion years of travel.”
