What is it about?
Hydrogen is a renewable energy with an enormous amount of energy that can not be thought of. In order to guarantee the stability of hydrogen, which is promising as a renewable energy, the hydrogen gas sensor that we have studied uses the excellent electric and electronic characteristics of AlGaN / GaN on Si heterostructure to measure even a small amount of hydrogen gas, Hydrogen gas sensor

Why is it important?
This is because the hydrogen gas sensor is the sensor that can be used to safely use the hydrogen that is attracting attention as a new and renewable energy, and to detect the hydrogen even in a very small amount of hydrogen in order to ensure its safety.
Perspectives
It is expected that a faster and more accurate sensor can be developed by using heterostrucre which is a compound semiconductor.
