Gallium to Boom

In 2024, the field of gallium nitride (GaN) is indeed experiencing significant developments and garnering attention. Let’s explore some key aspects:

1. GaN Semiconductors:
   • Advantages: GaN semiconductors offer substantial benefits over traditional MOSFETs (Metal-Oxide-Semiconductor Field-Effect Transistors). These advantages include faster switching speeds and lower ON resistances.
   • Electrical Efficiency: End products that incorporate GaN are more electrically efficient compared to those using last-generation MOSFETs¹.
2. Cubic Gallium Nitride:
   • Researchers have made strides in synthesizing high-quality, single-phase cubic gallium nitride. This material has low defect density and holds promise for various applications².
3. Wide Bandgap Materials:
   • GaN, along with silicon carbide (SiC), is part of the wide bandgap materials revolution. These materials are gradually replacing silicon in power electronics.
   • Silicon carbide and gallium nitride are poised to transform multibillion-dollar markets, signaling a shift away from traditional silicon dominance³.

While the graphene revolution faced challenges due to scaling up production, GaN technology is making strides. Keep an eye on GaN’s impact in electronics, power devices, and beyond!
