SiC fiasco favours GaN – Elektroniktidningen

GaN can be doped with silicon (Si) or with oxygen to n-type and with magnesium (Mg) to p-type. However, the Si and Mg atoms change the way the GaN crystals grow, introducing tensile stresses and making them brittle. Gallium nitride compounds also tend to have a high dislocation density, on the order of 10 8 to 10 10 defects per square centimeter. The global electronics industry has been fueled by silicon from the get-go, but that may soon change. Products are slowly appearing that replace silicon with While gallium nitride has a better performance in high energy and high heat applications than silicon, it is extremely cumbersome to produce incurring significantly higher financial costs.

Gallium Nitride And Silicon Carbide Power Devices - B Jayant

Silicon carbide (SiC), gallium nitride (GaN), aluminium nitride (AlN) or aluminium gallium nitride (AlGaN) "substrates", or ingots, boules, or other preforms of  Silicon has an electron mobility of 1500 cm 2 /Vs, while gallium nitride has an electron mobility of 2000 cm 2 /Vs. Therefore, the electrons in gallium nitride crystals can move over 30% faster than silicon's electrons. This electron mobility gives gallium nitride a distinct advantage for use in RF components, as it can handle higher switching frequencies than silicon. The table below compares material properties for Silicon (Si), Silicon Carbide (SiC-4H1) and Gallium Nitride (GaN). These material properties have a major influence on the fundamental performance characteristics of the devices.

This article Gallium nitride transistors have emerged as a high-performance alternative to silicon-based transistors, thanks to the technology's ability to be made allow smaller device sizes for a given on-resistance and breakdown voltage than silicon. After years of R&D in the lab, compound semiconductor materials like silicon carbide (SiC) and gallium nitride (GaN) used for ICs are taking a bigger role in handling electrical power.
