Claim Text:
1. A light emitting heterostructure comprising: an n-type contact layer formed of a group III nitride material; and a light generating structure adjacent to the n-type contact layer, the light generating structure formed within a group III nitride material having an aluminum molar fraction greater than fifty percent and forming a conduction band energy tub with respect to the n-type contact layer and including a plurality of quantum wells, wherein a difference between a conduction band edge energy of the n-type contact layer and an electron ground state energy of a quantum well in the plurality of quantum wells is greater than an energy of a polar optical phonon in a material of the light generating structure, and wherein a width of the light generating structure is comparable to a mean free path for emission of a polar optical phonon by an electron injected into the material forming the conduction band energy tub.
