Silicon nanocrystals free-standing

Free-Standing Silicon Nanocrystals from Porous Silicon... [Pg.428]

Highly monodisperse ZnSe nanocrystallites (NCs) were deposited on free-standing porous silieon. Optical phonons confined in nearly spherical ZnSe QDs have been studied theoretically and experimentally. Spatially quantized phonon modes are considered in the framework of the continuum model. Raman scattering and absorption of far-infrared (FIR) radiation in ZnSe quantum dots have been studied. Experimental FTIR transmittance spectra of porous silicon free layers containing nearly spherical ZnSe nanocrystals show a broad band between the bulk TO and LO phonon frequencies. [Pg.107]
