Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 11:
12. A light-emitting diode, comprising:
an N-type cladding layer;
a superlattice structure disposed on said N-type cladding layer;
an active layer directly disposed on said superlattice structure;
a P-type electron-blocking layer disposed on said active layer; and
a P-type cladding layer disposed on said P-type electron-blocking layer,

wherein:
said superlattice structure includes a first superlattice unit that contains a plurality of first periodical layered elements, each of said first periodical layered elements having a sub-layer which is made of a nitride-based semiconductor material including Al, and which has an energy band gap greater than that of said electron-blocking layer; and
said P-type electron-blocking layer is made of a nitride-based semiconductor material including Al, and has an energy band gap greater than that of said P-type cladding layer.
