The lattices of these semiconductor light emitting diode is typically InGaN-based doped by minor portions of magnesium to generate enough defects for radiation recombination of electrons and holes. For example, Nichia has made a 100 mW InGaN-based semiconductor light source designated NCCU033E, and ...
