Silicon has been the kingpin of the semiconductor industry for a long time. And it should be: it has an ideal crystal structure for use as a semiconductor, But in today's world where ultra-low power and an extremely small package are two important factors in electronics design, maybe silicon has sort of reached its limits. What's the alternative?
As a semiconductor material, gallium nitride (GaN) is getting the attention that silicon once had. GaN works will in high voltage and high temperature applications. Plus it has high switching frequencies than silicon and attractive for its high energy efficiency.
So, how will GaN change the world of electronics design in the next decade?
