In typical conditions of diamond film synthesis in a EACVD device ~JllectronAssisted Chemical Vapor Deposition), we report on the sudden jumps, bistability, multistability and negative resistance phenomena in methane-hydrogen mixture discharge plasma. We studied the variations of these phenomena with gas pressure, filament current. The difference of discharge characteristic between pure hydroge...

An efficient method is developed for the synthesis of single crystalline fibrous phosphorus submicron materials. Via the chemical vapor deposition (CVD) technique, fibrous phosphorus fibers with diameters from ∼150 nm to 2 μm were prepared directly from amorphous red phosphorus. The as-prepared fibrous phosphorus exhibited interesting photocatalytic properties.

High-quality single-walled carbon nanotubes (SWCNTs) have been synthesized from H2–CH4 mixtures on a MgO-supported bimetallic Mo/Co catalyst using microwave plasma-enhanced chemical vapor deposition (PECVD). Reaction parameters including temperature, H2:CH4 ratio, plasma power, and synthesis time have been examined to assess their influence on SWCNT synthesis. Raman spectroscopy and high-resolu...

Initiated chemical vapor deposition (iCVD) was explored as a novel method for synthesis of functional polyacrylic thin films. The process introduces a peroxide initiator, which can be decomposed at low temperatures (<2000 C) and initialize addition reaction of monomer species. The use of low temperatures limits the decomposition chemistry to the bond scission of initiator, while retaining funct...

Using a conventional thermal chemical vapor deposition (CVD) system, ethanol vapor was enclosed in a reactor, i.e., no flow, with Co/Mo dip-coated quartz substrates to synthesize submillimeter long vertically aligned single-walled carbon nanotube (SWNT) films successfully. The no-flow CVD method yielded an increase in film thickness of up to 0.11 mm compared with the normal flowing gas method f...

One-dimensional a-Fe2O3 is a promising nanomaterial for advanced applications in catalysis and water splitting, environmental protection, sensors, dye solar cells, magnetic storage media, bioprocessing, and controlled drug delivery and detection, especially as carriers of antigens for prion detection and PCR manipulation. a-Fe2O3 nanowires have been successfully synthesized by various methods b...

Abstract The physical properties of carbon materials can be altered by doping. For instance, the electronic graphene modulated controlling substitutional doping lattice with N. In addition, C–N bonding configurations three ring types are recognized: pyridinic-N, pyrrolic-N, and graphitic-N. Controlling type relative density various N is an important objective that requires extremely high level ...
