摘要: A method of manufacturing a nitride semiconductor light-emitting element includes: growing an n-side superlattice layer that includes InGaN layers and GaN layers; and, after the step of growing the n-side superlattice layer, growing a light-emitting layer. The step of growing the n-side superlattice layer comprises repeating a cycle n times (n is a number of repetition), the cycle including growing one InGaN layer and growing one GaN layer. In the step of growing the n-side superlattice layer, the step of growing one GaN layer in each cycle from a first cycle to an mth cycle is performed using carrier gas that contains N2 gas and does not contain H2 gas. The step of growing one GaN layer in each cycle from a (m+1)th cycle to an nth cycle is performed using gas containing H2 gas as the carrier gas.

摘要: Quantum dots that are cadmium-free and/or stoichiometrically tuned are disclosed, as are methods of making them. Inclusion of the quantum dots and others in a stabilizing polymer matrix is also disclosed. The polymers are chosen for their strong binding affinity to the outer layers of the quantum dots such that the bond dissociation energy between the polymer material and the quantum dot is greater than the energy required to reach the melt temperature of the cross-linked polymer.
