Abstract:
Synthesis of Carbon Nanostructures by Plasma Enhanced Chemical Vapour Deposition at Atmospheric PressureCarbon nanostructures present the leading field in nanotechnology research. A wide range of chemical and physical methods was used for carbon nanostructures synthesis including arc discharges, laser ablation and chemical vapour deposition. Plasma enhanced chemical vapour deposition (PECVD) with its application in modern microelectronics industry became soon target of research in carbon nanostructures synthesis. Selection of the ideal growth process depends on the application. Most of PECVD techniques work at low pressure requiring vacuum systems. However for industrial applications it would be desirable to work at atmospheric pressure. In this article carbon nanostructures synthesis by plasma discharges working at atmospheric pressure will be reviewed.

Full text
Abstract:
A detailed study has been made of the atmospheric pressure chemical vapour deposition (CVD) of tungsten carbide coatings onto powder metallurgy (PM) BT42 grade high speed steel (HSS) indexable cutting tool inserts. The pyrolysis of tungsten hexacarbonyl (W(CO)6) deposition route was utilised in conjunction with a laboratory-scale hot-wall CVD reactor. After numerous coating runs, deposition conditions were established under which rudimentary tungsten carbide coatings could be deposited at 350°C. The characteristics of these coatings were determined using an established characterisation procedure. This involved the following techniques: X-ray diffraction, ball cratering, Auger electron spectroscopy (AES), optical microscopy, fractography/scanning electron microscopy (SEM), profilometry, scratch adhesion testing and micro-indentation hardness testing.

Low loss optical waveguide structures combining the high bandwidth of light transmission and the economics of silicon substrates have been made possible by Low Pressure Chemical Vapor Deposition (LPCVD). This work explores the fabrication, modeling, and testing of LPCVD Si Ge waveguides. Thesis research was conducted during a six-month internship at Applied Materials, a semiconductor equipment manufacturing company. The present work can be divided into two parts: developmental work on the Applied Materials' Epi Centura® LPCVD reactor and use of this reactor to fabricate optical waveguides. Development was performed on the reactor to improve its performance for the deposition of epitaxial SiGe films in several essential aspects. The wafer heating and flow uniformity was given greater flexibility by employing a 3-zone heating lamp module, AccuSETT® flow controllers, and flow baffles. 1 [sigma]58% was achieved for thickness uniformity. The incorporation of an in-line purifier in the GeH.t supply line was found to reduce the oxygen concentration below the SIMS detection limit. Process conditions were identified for seleclive silicon epitaxial growth on silicon surfaces and not on oxide surfaces. Atomic force microscopy was used to characterize the surface roughness of polycrystalline SiGe films deposited-on nitride and oxide layers. The effect of C incorporation on the suppression of B diffusion was confirmed using this reactor. The addition of C to the SiGe lattice was shown to nullify the strain associated with epitaxial deposition on Si. Using the optimized reactor, optical waveguides were fabricated to determine the optimum processing conditions to produce low transmission loss structures. XRD scans on these samples confirm that low Ge concentration and relaxed structures were fabricated. Attenuation measurements in straight waveguide sections confirm that low loss transmission is achievable. The basic equations of optical transmission in planar waveguides are presented and solved for square cross-section strip SiGe waveguide design. The Marcatili method was used to model the electric field mode profiles in the waveguide core and cladding. Curved structures were designed to explore the crosstalking and coupling effects between adjacent waveguides.

Abstract:
Monolayers of molybdenum disulphide MoS2, a two dimensional (2D) semiconductor with a direct band gap of 1.9 eV, have been proposed as a candidate for next generation nanoscale electronic and opto-electronic devices. Controlled synthesis of MoS2 monolayers is critically important since the thickness uniformity and grain size are major concerns for the fabrication of opto-electronic devices. In this study, we demonstrated the growth of wafer scale uniform MoS2 monolayers on SiO2 covered silicon wafers, at a range of growth temperatures (650 oC-850 oC) with optimum grain sizes as large as 400 μm, using low pressure chemical vapor deposition (LPCVD). By controlling the partial pressure of the reactant species at the growth surface and the limiting time, we can achieve prefered monolayer growth over multilayer growth. The MoS2 monolayer crystals follow a lognormal size distribution, consistent with random crystal nucleation, with single crystal domains as large as 400 μm. We estimated the thermal expansion coefficient to be (2.5±1.2) ×10-6 /oC, which is at least double that of the bulk. We have found film growth can be clearly classified into the reaction limited, feed limited and desorption limited regimes. With the help of COMSOL simulations, we have related the local growth environment such as growth temperature, MoO2 concentration, sulphur chemical potential and growth time with the macroscopic growth parameters such as Ar flux. In the feed limited regions, it is the supply of Mo that is the rate limiting factor. In the desorption regions, the growth is controlled by thermal stability of MoS2 monolayers. The growth modes also can be used to tune the grain morphology from perfect triangles to hexagons. Finally, we have also compared our approach with an LPCVD approach based on MoO3 as the Mo source. MoO3 has a higher vapor pressure than MoO2 which was used in the previous approach. By tuning the the S:MoO3 ratio, we could grow controllably planar MoS2 monolayers, vertically aligned MoS2/MoO2 and planar MoO2 crystals.

Successfully integrating graphene in standard processes for applications in electronics relies on the synthesis of high-quality films. In this work we study Low Pressure Chemical Vapor Deposition (LPCVD) growth of bilayer graphene on the outside surface of copper enclosures. The effect of several parameters on bilayer growth rate and domain size was investigated and high-coverage bilayers films were successfully grown. Furthermore, the quality of the bilayer was confirmed using Raman spectroscopy. Finally, we consider future studies that may reveal the underlying mechanisms behind bilayer growth.

Abstract:
Abstract Chemical vapor deposition processes are one of the most used techniques for depositing thin films in the semiconductor-microelectronics and opto-electronic industries. Particulate contamination of the substrate during these CVD processes can be detrimental to the product yield. Due to the temperature gradients present in the CVD reactor, thermophoresis has a direct impact on the amount of particulate deposition on the substrate. The thermophoretic force is the force that arises from asymmetrical interactions of a particle with the surrounding gas molecules due to a temperature gradient. CVD processes can take place in hot and cold wall reactors, with varying substrate temperatures. This array of thermal boundary conditions results in a variety of temperature gradients and thermophoretic forces on the particle. There are other forces also acting on the particles in the CVD environment such as the Brownian force, drag, and gravity. The effect of thermophoresis on the particle transport and deposition in the reactor is examined. Different particle concentrations and sizes is considered in the reactor. The motion of these particles according to the thermal gradients in the reactor is examined. The behavior of these particles under different thermal conditions is studied.

Full text
Abstract:
The Montney Formation in Alberta and British Columbia, Canada is an early Triassic siltstone currently in an active diagenetic environment at depths greater than 1,000 m, but with maximum burial depths potentially exceeding 5,000 m (Ness, 2001). It has undergone multiple phases of burial and uplift and there is strong evidence for multiple generations of hydrocarbon maturation/migration. Understanding the origin and history of diagenetic fluids within these systems helps to unravel the chemical changes that have occurred since deposition. Many cores taken near the deformation front display abundant calcite-filled fractures including vertical or sub-vertical, bedding plane parallel (beefs), and brecciated horizons with complex mixtures of vertical and horizontal components. We analyzed vertical and brecciated horizons to assess the timing and origin of fluid flow and its implications for diagenetic history of the Montney Fm. Aqueous and petroleum bearing fluid inclusions were observed in both vertical and brecciated zones; however, they did not occur in the same fluid inclusion assemblages. Petroleum inclusions occur as secondary fluid inclusions (e.g. in healed fractures and along cleavage planes) alongside primary aqueous inclusions indicating petroleum inclusions post-date aqueous inclusions and suggest multiple phases of fluid flow is recorded within these fractures. Raman spectroscopy of aqueous inclusions also display no evidence of petroleum compounds supporting the absence or low abundance of petroleum fluids during the formation of aqueous fluid inclusions. Pressure-corrected trapping temperatures (>140°C) are likely associated with the period of maximum burial during the Laramide orogeny based on burial history modelling. Ice melt temperatures of aqueous fluid inclusions are consistent with 19% NaCl equiv. brine and eutectic temperatures (-51°C) indicate NaCl-CaCl2 composition. Combined use of aqueous and petroleum fluid inclusions in deeply buried sedimentary systems offers a promising tool for better understanding the diagenetic fluid history and helps constrain the pressure-temperature history important for characterizing economically important geologic formations.
