DOI: 10.1134/s1028335817060039
Abstract: The theory of modification of surface Tamm states on fractal surfaces is developed, and manifestations of such phenomena are analyzed. The obtained results suggest that the fractality of free and inner surfaces of nanoobjects affects… read more here.

DOI: 10.3390/nano13040696
Abstract: We observed resonance effects in the Raman scattering of nanodiamonds with an average size of 2–5 nm excited at a wavelength of 1064 nm (1.16 eV). The resonant Raman spectrum of the 2–5 nm nanodiamonds… read more here.
