CVD growth of boron-rich nanostructures

Controlled CVD growth of Cu-Sb alloy nanostructures.

Sb based alloy nanostructures have attracted much attention due to their many promising applications, e.g. as battery electrodes, thermoelectric materials and magnetic semiconductors. In many cases, these applications require controlled growth of Sb based alloys with desired sizes and shapes to achieve enhanced performance. Here, we report a flexible catalyst-free chemical vapor deposition (CVD...

Microwave Synthesis of Boron Nitride Nanostructures

One dimensional boron nitride nanostructures promise many interesting applications in biomedical, semiconductor and hydrogen storage and other fields. We have synthesized Boron Nitride in various nanoforms by a high temperature solid state reaction between boric acid and urea in a commercial microwave furnace. The formation of boron nitride was established from the binding energies for boron an...

CVD growth of carbon nanostructures from zirconia: mechanisms and a method for enhancing yield.

By excluding metals from synthesis, growth of carbon nanostructures via unreduced oxide nanoparticle catalysts offers wide technological potential. We report new observations of the mechanisms underlying chemical vapor deposition (CVD) growth of fibrous carbon nanostructures from zirconia nanoparticles. Transmission electron microscope (TEM) observation reveals distinct differences in morpholog...

Dependence of boron incorporation in delta layers on CVD diamond growth process and misorientation angle

Diamond is a promising material for the next generation of high-power and high-frequency semiconductor devices. In terms of its physical properties: high carrier saturation velocity (2.7·10 cm/s), high electron and hole mobility at low doping level, and record thermal conductivity, diamond significantly exceeds other semiconductor materials. Diamond is a wide-band gap semiconductor/insulator (b...
