Аннотация:Using the model of oscillating dipoles, we simulated the photoluminescence intensity of a
triple-layered structure where the silicon nanocrystals layer was enclosed by buffer and capping
silicon dioxide layers. It was found that a structure with an optimized buffer layer thickness exhibited
photoluminescence which was approximately 20 times more intense than that from the structure
without a buffer layer. Theoretical simulations were verified by photoluminescence measurements
for the corresponding structures with silicon nanocrystals fabricated by plasma enhanced chemical
vapour deposition.
