Content &Introduction 
     Transparent conducting current-spreading layer is important for the quantum efficiency and thermal performance of light-emitting diodes (LEDs). The demand for tin-doped indium oxide (ITO) caused the price greatly increasing. Super-aligned carbon nanotubes (SACNTs) and Au-coating SACNTs as current-spreading layer were applied on AlGaInP LEDs. The LEDs with Au-coating SACNTs showed good current spreading effect.The voltage bias at 20mA dropped about 0.15V and the optical power increased about 10% compared with the LEDs without SACNTs.
