GaN-based Single chip white light emitting diode epitaxial material

The invention relates to GaN-based Single chip white light emitting diode epitaxial material comprising a substrate and also comprising an initial growth layer, an intrinsic GaN buffer layer, an n-type GaN layer, a stress relaxation layer, an InGaN multiple quantum well structure light emitting layer, a p-type AlGaN sandwich layer and a p-type GaN layer which grow in sequence on the substrate. Thestress relaxation layer is an InGaN/GaN superlattice stress modulation layer which comprises InGaN layers and GaN layers, which are grown alternatively; the InGaN layers and GaN layers have the growth cycle of 6-500 and the corresponding thickness of 10 nm to 3 Mum; and the In components in the InGaN layers are in the range of 1-35 percent. Because the stress-relaxed InGaN/GaN superlattice stressmodulation layer is added between the n-type GaN layer and a multiple quantum light emitting layer, the In segregation effect is strengthened, InGaN quantum dots with different components are formed,and the mixing of different-wave light emitted by the InGaN quantum dots realizes the white light emitting. The cost of the white light emitting diode is reduced radically, the light emitting efficiency and the light using efficiency are increased and the integral performance of the white light emitting diode is improved.

Reactor for extended duration growth of gallium containing single crystals

An apparatus for growing bulk GaN and AlGaN single crystal boules, preferably using a modified HVPE process, is provided. The single crystal boules typically have a volume in excess of 4 cubic centimeters with a minimum dimension of approximately 1 centimeter. If desired, the bulk material can be doped during growth to achieve n-, i-, or p-type conductivity. In order to have growth cycles of sufficient duration, preferably an extended Ga source is used in which a portion of the Ga source is maintained at a relatively high temperature while most of the Ga source is maintained at a temperature close to, and just above, the melting temperature of Ga. To grow large boules of AlGaN, preferably multiple Al sources are used, the Al sources being sequentially activated to avoid Al source depletion and excessive degradation. In order to achieve high growth rates, preferably a dual growth zone reactor is used in which a first, high temperature zone is used for crystal nucleation and a second, low temperature zone is used for rapid crystal growth. Although the process can be used to grow crystals in which the as-grown material and the seed crystal are of different composition, preferably the two crystalline structures have the same composition, thus yielding improved crystal quality.
