▎ 摘 要
NOVELTY - The LED has an N-type semiconductor layer positioned on a substrate, and an active layer positioned on the N-type semiconductor layer. A p-type semiconductor layer is positioned on the active layer. A current spreading layer is positioned on the P-type semiconductor layer. A transparent electrode is positioned on the current spreading layer. A P-type contact part is positioned on the transparent electrode. An N-type electrode is positioned on the N-type semiconductor layer, where the transparent electrode is made of graphene. USE - LED. ADVANTAGE - The transparent electrode is made of graphene having conductive impurity, so that the LED has improved current characteristic and transmission efficiency in UV range at all areas till infrared range. DESCRIPTION OF DRAWING(S) - The drawing shows a top perspective view of a LED.
