For non-metallic crystalline materials including gallium nitride (GaN), heat is conducted mostly through lattice vibrations (phonons). Therefore, the thermal conductivity can be reduced by anything that affects phonon physics, which includes disloions and other extended defects, intrinsic point defects such as vacancies and antisites, and extrinsic defects (impurities).

It also has much higher bandgaps than other potential silicon replacements such as silicon carbide (SiC) with 3.4 electron volts and gallium nitride with 3.3 electron volts. This time, the researchers decided to base a MOSFET on gallium oxide and found that despite its super small and thin profile thanks to the ultrawide bandgap, their transistor was able to handle extremely high voltages of
Silicon carbide ceramics with little or no grain boundary impurities maintain their strength to very high temperatures, approaching 1600 C with no strength loss. Chemical purity, resistance to chemical attack at temperature, and strength retention at high temperatures has made this material very popular as wafer tray supports and paddles in semiconductor furnaces.
