Abstract:
1. A nitride compound semiconductor light emitting device comprising: a GaN substrate having a Ga-face crystal orientation tilted away from a <0001> direction in a direction such that a tilt angle between the <0001> direction and one or more of the <11-20> and <1-100> directions is equal to or greater than 0.05° and less than 2°; a n-type layer containing a nitride compound semiconductor located above the GaN substrate; an active layer containing a nitride compound semiconductor located above the GaN substrate; an acceptor doping layer containing a nitride compound semiconductor comprising Ga wherein the GaN substrate and the active layer are formed so as to be apart from each other by a distance which is equal to or greater than about 1 μm.
