Journal ArticleDOI
Formation of nanotubes and hollow nanoparticles based on Kirkendall and diffusion processes: a review.
TL;DR: This Review summarizes and discusses the demonstrated examples of hollow nanoparticles and nanotubes induced by the Kirkendall effect and merits of this route are compared with other general methods for nanotube fabrication.
Journal ArticleDOI
Semiconductor nanowires: from self-organization to patterned growth
TL;DR: This Review discusses the various growth processes, with a focus on the vapor-liquid-solid process, which offers an opportunity for the control of spatial positioning of nanowires.
Journal ArticleDOI
Size-controlled highly luminescent silicon nanocrystals: A SiO/SiO2 superlattice approach
TL;DR: In this article, the size control of SiO/SiO2 superlattices with an upper limit of the nanocrystal sizes of 3.8, 2.5, and 2.0 nm was investigated.
Journal ArticleDOI
Monocrystalline spinel nanotube fabrication based on the Kirkendall effect
Hong Jin Fan,Mato Knez,Roland Scholz,Kornelius Nielsch,Eckhard Pippel,Dietrich Hesse,Margit Zacharias,Ulrich Gösele +7 more
TL;DR: This letter reports, for the first time, on ultra-long single-crystal ZnAl2O4 spinel nanotubes fabricated through a spinel-forming interfacial solid-state reaction of core-shell ZnO–Al 2O3 nanowires involving the Kirkendall effect.
Journal ArticleDOI
Classification and control of the origin of photoluminescence from Si nanocrystals
S. Godefroo,Manus Hayne,Manus Hayne,Mihaela Jivanescu,Andre Stesmans,Margit Zacharias,Oleg I. Lebedev,G. Van Tendeloo,Victor Moshchalkov +8 more
TL;DR: It is shown, based on measurements in high magnetic fields, that defects are the dominant source of light from Si nanocrystals, and it is shown that it is possible to control the origin of the photoluminescence in a single sample.
