We study Raman spectra of ZnO nanoparticles of 5–12 nm size in the whole range of the first-
order phonon bands. We apply the 3D phonon confinement model (PCM) for the …

Spectroelectrochemistry (SEC) is a set of techniques with many advantages in the study and
characterization of materials. Although SEC has not yet been widely used to study quantum …

Several approaches may be used to link the Raman spectra to the characteristic size scale
of nanomaterials. To treat the vibrations of the nanocrystal as localized phonons is a basic …

The investigation of surface-induced lattice-strain effects in free-standing silicon
nanocrystals (Si NCs) is fundamental in view of the materialization of nanosilicon-based …

Raman spectroscopy is a powerful method that gives insight into the atomic structure and
composition of nanomaterials, but also allows to draw conclusions about their electronic …

We show that nanocrystals share a common and intrinsic skin electric-double-layer (EDL).
The EDL is determined to be 2.14 regular-bond-length thick using differential phonon …

The mechanisms of recombination of photo-generated charge carriers and the origin of
luminescence in silicon nanocrystals, quantum dots or nanoparticles (Si-NPs) are essential …

As a two-dimensional carbon based semiconductor, C 3 N acts as a promising material in
many application areas. However, the basic physical properties such as Raman spectrum …

Solution-processed thin films of crystalline silicon nanoparticles (Si NPs) have a great
potential for a wide variety of electronic and optoelectronic applications. However, such films …

We report a classical molecular-dynamics simulation of models of silicon nanoparticles and
bulk silicon, in both the crystalline and the amorphous phase, to investigate their vibrational …
