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

Claim 0:
1. A nitride semiconductor light-emitting element comprising:
an n-side nitride semiconductor layer;
a p-side nitride semiconductor layer; and
an active layer between the n-side nitride semiconductor layer and the p-side nitride semiconductor layer,
wherein the active layer comprises:
one or more well layers comprising a first well layer that is nearest to the n-side nitride semiconductor layer, and
one or more barrier layers comprising a first barrier layer between the first well layer and the n-side nitride semiconductor layer,

wherein the first barrier layer comprises a Si-doped InGaN barrier layer and an undoped GaN barrier layer in this order from the n-side nitride semiconductor layer side, and
wherein, in the Si-doped InGaN barrier layer, a doping amount of Si at a central portion of the Si-doped InGaN barrier layer is greater than a doping amount of Si at the n-side nitride semiconductor layer side of the Si-doped InGaN barrier layer and a doping amount of Si at a well layer side of the Si-doped InGaN barrier layer.
