Gallium nitride has a 3.4 eV bandgap, compared to silicon’s 1.12 eV bandgap. Gallium nitride’s wider band gap means it can sustain higher voltages and higher temperatures than silicon MOSFETs. This wide bandgap enables gallium nitride to be applied to optoelectronic high-power and high-frequency devices.

Anker has debuted its tiny new power brick, and the company is crediting its small size with the component it uses instead of silicon: gallium nitride (GaN). It’s the latest example of the growing The leading candidate for taking electronic performance to the next level and a reactivation of positive momentum of Moore’s Law is gallium nitride. GaN’s ability to conduct electrons more than 1000 times more efficiently than silicon, while being able to be manufactured at a lower cost than silicon has now been well established. Silicon is out of gas, and a new, higher performing semiconductor material is emerging – GaN is on the rise.

Graphene has shown great promise to fix this issue. One of graphene’s outstanding properties is its ability to take on the characteristics of other materials. Galium nitride is wide band-gap semiconductor with a direct gap. It is derived from well known galium arsenide which is a widely used semiconductor industrially, mainly for the purpose of light generation and lasers.
