Abstract
A white LED includes a P-type layer, a tunneling structure, an N-type layer, an N-type electrode, and a P-type electrode. The tunneling structure is in contact with the P-type layer. The tunneling structure is a stack structure comprising a first barrier layer, a first active layer and a second barrier layer. At least one of the first barrier layer, the first active layer and the second barrier layer is a first metal nitride oxide layer. The N-type layer is in contact with the tunneling structure. The N-type electrode is in contact with the N-type layer. The P-type electrode is in contact with the P-type layer.
