In the present paper, we present results of thermal conductivity measurements in commercially-available, chemical vapor deposition grown, heat-treated and non-heat-treated individual carbon nanofibers (CNFs). The thermal conductivity measurements are made using the T-type probe experimental configuration using a Wollaston wire probe inside a high resolution scanning electron microscope. The res...

The metalorganic chemical vapor deposition (MOCVD) process for electronic and photonic compound semiconductor materials and devices is reviewed. We begin with an introduction to the basic MOCVD chemical reaction process, gas delivery equipment, reaction chambers, and safety. Growth mechanisms, including hydrodynamics, boundary-layer issues, thermal effects, and pyrolysis reactions, are defined,...

Hexagonal boron nitride (hBN) is a layered material with high thermal and chemical stability ideal for ultrathin corrosion resistant coatings. Here, we report the corrosion resistance of Cu with hBN grown by chemical vapor deposition (CVD). Cyclic voltammetry measurements reveal that hBN layers inhibit Cu corrosion and oxygen reduction. We find that CVD grown hBN reduces the Cu corrosion rate b...

Chemical vapor deposition (CVD) is an established, versatile technique for the preparation of high-quality metal and semiconductor thin films on solid surfaces.1,2 Despite its utility, constraints inherent to the process, including the requirement of high precursor vapor pressure and thermally coupled transport and deposition steps, generally preclude its use at low temperature and for non-line...

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...

in this research carbon nanotubes were produced by chemical vapor deposition of acetylene over a mixture of iron and cobalt catalysts supported on nanometric tio2 and the influences of two synthesis parameters: growth temperature and catalyst composition ratio on properties of end-product carbon nanotubes were investigated. the catalytic basis was prepared by wet impregnation method with differ...

a simple chemical vapor deposition technique at atmospheric pressure (apcvd) is adopted to synthesize the aligned arrays of functionalized multi-walled carbon nanotubes (amwcnts) without using any carrier gas, at 230◦c, 750◦c and 850 ◦c. camphor (c10h16o) is used as carbon source because this botanical hydrocarbon is chip and abundant which convert the cvd technique to a green method for produc...

multi-walled carbon nanotubes (mwnt’s) were synthesized using chemical vapor deposition (cvd) method in a fluidized bed reactor under the flow of methane and hydrogen gases. a cobalt-molybdenum/magnesium oxide (co-mo/mgo) nanocatalyst was used as the catalyst of the process. the samples were analyzed using scanning electron microscopy (sem) and x-ray diffraction (xrd) analyses. the effects of d...

Antennas are devices for transmitting and/or receiving signals which make them a necessary component of any wireless system. In this paper, a thermal deposition technique is utilized as a method to fabricate antenna structures on substrates. Thin-film deposition is achieved by evaporating a source material (metals in our case) in a vacuum which allows vapor particles to travel directly to the t...
