Abstract:
1. A semiconductor light emitting device, comprising: an n-type layer comprising a nitride semiconductor; a p-type layer comprising a nitride semiconductor; and a stacked structure provided between the n-type layer and the p-type layer and comprising: wherein: at least one of the barrier layers comprises a first portion layer and a second portion layer, the first portion layer being disposed on a side of the n-type layer, and the second portion layer being disposed on a side of the p-type layer, and comprising an n-type impurity with a concentration higher than an n-type impurity concentration in the first portion layer; and at least one of the well layers comprises a third portion layer and a fourth portion layer, the third portion layer being disposed on a side of the n-type layer, and the fourth portion layer being disposed on a side of the p-type layer, and comprising the n-type impurity with a concentration higher than an n-type impurity concentration in the third portion layer.
