The　performance　and　characteristics　of　resonant-cavity　light-emitting　diodes　(RCLEDs)　are　obviously　affected　by　p-electrode　shape,　since　the　RCLEDs　are　lack　of　the　current　spreading　layer.　The　oxide-confined　RCLEDs　with　two　types　of　p-electrode　have　been　fabricated.　By　comparing　characteristics　of　the　two　types　of　RCLEDs,　the　voltage　at　20mA　of　the　RCLED　with　single　ring　electrode　is　0.5V　greater　than　that　with　double　rings.　At　20mA,　the　light　output　power　of　the　RCLEDs　with　the　single　ring　electrode　and　the　double　ring　electrode　is　respectively　1.228mW　and　1.094mW.　Light　output　power　saturation　rate　of　RCLED　with　the　single　ring　is　faster　than　that　with　the　double　rings.　At　low　current,　since　the　influence　of　heat　effect　on　the　device　performance　is　not　obvious　and　the　single　ring　electrode　has　better　light　extraction　for　larger　emitting　area,　the　light　output　power　of　RCLED　with　the　single　ring　is　higher　than　that　with　the　double　rings.　At　high　current,　as　the　influence　of　heat　effect　is　dominant　as　compared　with　light　extraction　and　the　single　ring　electrode　has　greater　heat　effect　for　smaller　ohmic　contact　area,　the　light　output　power　of　RCLED　with　the　single　is　lower　than　that　with　the　double　rings.　The　great　heat　generated　affects　the　device　reliability.　In　conclusion,　RCLEDs　with　the　single　ring　electrode　has　greater　light　output　power　at　lowF　injected　current　but　worse　device　reliability　for　great　heat　effect.　©　2011　IEEE.
