The control of luminous radiation has extremely important implications for modern and future
technologies as well as in medicine. In this Review, we detail chemical structures and their …

Silicon quantum dots (SiQDs) hold great promise for many future technologies. Silicon is
already at the core of photovoltaics and microelectronics, and SiQDs are capable of efficient …

The role of quantum confinement (QC) in Si and Ge nanostructures (NSs) including quantum
dots, quantum wires, and quantum wells is assessed under a wide variety of fabrication …

Strong room-temperature photoluminescence (PL) in the wavelength range 650–950 nm
has been observed in high temperature annealed (1000–1300° C) substoichiometric silicon …

Si nanoclusters embedded in SiO 2 have been produced by thermal annealing of SiO x films
prepared by plasma enhanced chemical vapor deposition. The structural properties of the …

Silicon nanomaterials and nanostructures exhibit different properties from those of bulk
silicon materials based on quantum confinement effects. They are expected to lead to the …

Nanocrystals (NCs), representing a zero-dimensional system, are an ideal platform for
exploring quantum phenomena on the nanoscale, and are expected to play a major role in …

Never before has electricity been generated out of metal oxides without using any light
(UV/IR), acid, or alkali, but it has been achieved by adding a few drops of water on …

We have investigated phase separation, silicon nanocrystal (Si NC) formation and optical
properties of Si oxide (⁠ Si O x⁠, 0< x< 2⁠) films by high-vacuum annealing and dry …

Observation of optical gain in silicon nanocrystals (Si-nc) is critically dependent on a very
delicate balance among the Si-nc gain cross-sections, the optical mode losses and …
