Abstract：

This　paper　reports　a　new　method　of　fabricating　AlGaInP-based　nanorod　light　emitting　diodes　(LEDs)　by　using　self-assembly　metal　layer　nanomasks　and　inductively　coupled　plasma.　Light-power　measurements　indicate　that　the　scattering　of　photons　considerably　enhances　the　probability　of　escaping　from　the　nanorod　LEDs.　The　light-intensity　of　the　nanorod　LED　is　increased　by　34%　for　a　thin　GaP　window　layer,　and　by　17%　for　an　8　μm　GaP　window　layer.　The　light-power　of　the　nanorod　LED　is　increased　by　25%　and　13%,　respectively.　©　2010　Chinese　Institute　of　Electronics.
