Abstract:
1. A light emitting device having formed therein a light emitting layer section based on a double heterostructure in which a p-type cladding layer, an active layer and an n-type cladding layer, individually composed of a Mg a Zn 1-a O (0≦a≦1) type oxide, are stacked in this order, the device using a face on the n-type cladding layer side as a light extraction surface, and having, as being provided on the main surface on the light extraction surface side of the n-type cladding layer, an n-type low resistivity layer composed of a Mg a Zn 1-a O (0≦a≦1) type oxide, and having a content of an n-type dopant larger than that in the n-type cladding layer.
