Optical properties of clusters
Journal Title: Journal of Physics and Electronics - Year 2018, Vol 26, Issue 1
Abstract
In this paper, we discuss in detail the theoretical results obtained with using the local functional density method in parameteric approximation of silicon clusters. One of the main conclusions is that the comparison between theory and experiments shows the possibility of different radiative channels for the recombination in porous silicon.
