“…However, the TCN suggests that charged diamond nanoparticles are spontaneously generated in the gas phase and become the building block of diamond films. The generation of these hypothetical diamond nanoparticles was experimentally confirmed in the hot filament diamond CVD process using a Wien filter [48] and an energy analyzer [49,110]. If diamond nanoparticles are suspended in the gas phase during diamond CVD, they can be captured on a membrane of the TEM grid.…”

Nonclassical crystallization is the process in which crystals grow by deposition of nanoparticles rather than by the layer-wise deposition of atoms/ions/molecules on a crystal surface. A spontaneous generation of charged nanoparticles (CNPs) in the gas phase has been experimentally confirmed during many chemical vapor deposition (CVD) processes. The fact that crystals grown by CNPs have smooth surfaces without any void indicates that CNPs have a liquid-like or superplastic property. Based on this understanding of nonclassical crystallization in CVD processes, the synthesis of nanoparticles, thin films and nanowires can be approached systematically. Since electrical field, drag effect, size and the number of charges per particle affect the behavior of CNPs, electric bias, gas velocity, the size of the nanoparticles and the amount of charge can be new processing parameters. The size distribution of CNPs depends on the process conditions.The nanoparticles can be attracted or repelled by applying an electric bias to a substrate. If the nanoparticles are made to land on the substrate in a suitable number density, they can be used as quantum dots. In addition, nanopowders, nanowires, and nanostructures can be synthesized by CNPs with or without metallic catalysts on substrates. Herein, we will review recent results of the synthesis of nanostructures such as nanoparticles, thin films, and nanowires in the CVD process. We will also discuss the role of charge in these syntheses.

“…This concept was also applied to the low temperature deposition of crystalline silicon nitride at the substrate temperature of 700 1C using HWCVD [17]. This deposition mechanism is not only applicable to the silicon HWCVD process, but also to other processes such as CVD growth of diamonds [18,19], carbon nanotubes [20,21], silicon nanowires [22], and zinc oxide nanowires [17].…”
