Mass transport during laser chemical vapor deposition

Journal of Applied Physics, 1988
Two analyses of steady-state mass transport during laser chemical vapor deposition (LCVD) are compared for a hemispherical source/sink geometry. The first considers only diffusion while the second includes diffusion and also convection due to the mole number change of vapor species in the reaction, which is modeled as the radial outflow of an ...

Mass Transport Effects In Selectively Deposited Diamond Thin Films

MRS Proceedings, 1995
ABSTRACTIn order to study the effects of gas phase transport on the growth of hot-filament chemical vapor deposited (HFCVD) diamond, crystallites were selectively grown on a pre-nucleated, oxygen plasma patterned silicon wafer. Growth rate differences across the substrate were observed from scanning electron micrographs.

Mass Transport in Atomic Layer Deposition Carrier Gas Reactors

Journal of The Electrochemical Society, 1995
A detailed model for the operation of a flow type atomic layer deposition (ALD) reactor is developed and tested with the growth of tantalum pentoxide thin films. The model incorporates evaporation, diffusion, and convection phenomena in mass transport and a kinetic description of the surface reactions and film growth.

Morphometry of mass-transport deposits as a predictive tool

Geological Society of America Bulletin, 2015
Mass-transport deposits (MTDs) are gravity-induced units that represent an important component of modern and ancient deep-water stratigraphic successions. MTDs have been widely documented in the literature, but a comprehensive compilation of quantitative morphometric parameters associated with their external architecture is still lacking.

Mass-transport deposits within basinal carbonates from southern Italy

Italian Journal of Geosciences, 2016
A detailed characterisation of submarine mass-transport deposits (MTDs), in terms of both emplacement processes and internal architecture of depositional products, is crucial to define the hydraulic properties of slope-to-basinal deposits.The Late Jurassic-Early Cretaceous basinal Maiolica Formation exposed in the Gargano Promontory (southern Italy ...

Mass-Transport Deposits in Deepwater Settings

2011
Historically, submarine-mass failures or mass-transport deposits have been a focus of increasingly intense investigation by academic institutions particularly during the last decade, though they received much less attention by geoscientists in the energy industry.

Mass Transport Deposits on the Southwestern Newfoundland Slope

2010
Sediment mass failure is a major process during Cenozoic development of the southwestern Grand Banks of Newfoundland margin. Recently acquired seafloor multibeam and seismic reflection data provide evidence of stacked and regionally extensive mass transport deposits (MTDs) since the middle-late Miocene.

Minimum Stress Trends in Stacked Mass Transport Deposits, Deepwater Guyana

Second EAGE Workshop on Pore Pressure Prediction, 2019
Summary In pressure predictions for early Stabroek exploration wells, minimum stress was calculated using the Terzaghi soil mechanics method (Matthews and Kelly, 1967) and a standard range of effective stress ratios according to Shmin=K0(Sv-Pp)+Pp, where Shmin is minimum stress, Sv is the overburden, PP is the pore fluid pressure and K0 is the ...

Olistostromes, mélanges and mass-transport deposits

2010
The terms olistostrome and olistolith have been introduced by G. Flores (4th World Petroleum Congress, 1955, Rome) to indicate either sedimentary bodies with a chaotic block-in-Matrix fabric or single slide blocks, intercalated between layered sequences in the Tertiary succession of Sicily.

Convection and Mass‐Transport in Laser‐Induced Chemical Vapor Deposition

Journal of The Electrochemical Society, 1988
Gas flow and energy and species transport in laser-induced chemical vapor deposition (LICVD) of amorphous silicon films by silane pyrolysis are analyzed by finite element analysis of a two-dimensional model for the process. Spatial nonuniformity of the deposited film is shown to result from diffusion controlled transport of products between the beam ...
