Similar to its popular older cousins the fullerene, the carbon nanotube, and graphene, the
latest form of nanocarbon, the carbon nanodot, is inspiring intensive research efforts in its …

A large amount of work world-wide has been directed towards obtaining an understanding
of the fundamental characteristics of porous Si. Much progress has been made following the …

Depending on the size, the photoluminescence (PL) of silicon quantum dots present in
porous silicon can be tuned from the near infrared to the ultraviolet when the surface is …

The striking photoluminescence properties of porous silicon have attracted considerable
research interest since their discovery in 1990. Luminescence is due to excitonic …

This review seeks to extend the scope of both the experimental and theoreticalwork carried
out since I completed my 1993 review on the electronic, optical, andto a lesser extent, the …

This report deals with the mechanism behind the unusual behavior of nanostructures in
mechanical strength, thermal stability, acoustics (lattice dynamics), photonics, electronics …

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 …

X-ray absorption and photoemission spectra have been used to measure the band edges of
silicon nanocrystals with average diameters ranging from 1 to 5 nm. We compare the …

In this review, the emerging roles of group IV nanoparticles including silicon, diamond,
silicon carbide, and germanium are summarized and discussed from the perspective of …

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