Abstract:
A UV LED element, which is an exemplary ultraviolet light-emitting diode according to the present invention, includes an n-type conductive layer, a light-emitting layer, an electron block layer, and a p-type contact layer, all of which are arranged in this order. Bandgap energy of the electron block layer satisfies E contact ≤E EBL , where E contact  designates bandgap energy of the p-type contact layer and E EBL  designates the bandgap energy of the electron block layer. The electric apparatus includes the UV LED element as a light source for emitting an ultraviolet ray.

Claim (Index 10):
An ultraviolet light-emitting diode comprising:\n an n-type conductive layer including an In x1 Al y1 Ga 1-x1-y1 N layer (where 0\u2264x1<1 and 0<y1\u22641); a light-emitting layer; an electron block layer including an In x2 Al y2 Ga 1-x2-y2 N layer (where 0\u2264x2<1 and 0<y2\u22641); and a p-type contact layer including an In x3 Al y3 Ga 1-x3-y3 N layer (where 0\u2264x3<1 and 0<y3<1), all of which are arranged in this order, the ultraviolet light-emitting diode having a hole barrier height of 300 meV or less, the hole barrier height being defined by an energy difference between a maximum value of valence band energy of the electron block layer and a quasi-Fermi level value of holes.
