About Aluminium Gallium Nitride
Aluminium gallium nitride is a semiconductor material. It is any alloy of aluminium nitride and gallium nitride. The bandgap of AlₓGa1−xN can be tailored from 3. 4eV to 6. 2eV. AlGaN is used to manufacture light-emitting diodes operating in blue to ultraviolet region, where wavelengths down to 250 nm were achieved.
