4 inch N-type UID-doped GaN on sapphire wafer SSP resistivity＞0.5 Ω cm LED, laser, PIN epitaxial wafer
For example, GaN is the substrate which makes violet (405 nm) laser diodes possible, without use of nonlinear optical frequency-doubling. Its sensitivity to ionizing radiation is low (like other group III nitrides), making it a suitable material for solar cell arrays for satellites. Military and space applications could also benefit as devices have shown stability in radiation environments.
