Get this from a library. Numerical modeling of Bridgman growth of PbSnTe in a magnetic field. [Minwu Yao; United States. National Aeronautics and Space Administration.;]. The quality of large semiconductor crystals grown from the melt for use in electronic and optoelectronic devices is strongly influenced by the intricate coupling of.
Numerical Study of a Vertical Solidification Process under Magnetic Field in Unsteady State Article (PDF Available) in Defect and Diffusion Forum. The effects of an axially imposed magnetic field on convection and solute segregation during Bridgman growth of a non-dilute multicomponent system PbSn Te were studied using a finite-element.
bridgman growth and characterizaton of bulk single crystals of ga1-xinxsb for thermophotovoltaic applications. J.R. Boyer and W.T. Haines, Lockheed Martin, Inc., Schenectady, NY. Thermophotovoltaic generation of electricity is attracting renewed attention due to recent advances in low bandgap ( eV) III-V semiconductors.
Michael G. Mauk, in Handbook of Crystal Growth: Thin Films and Epitaxy (Second Edition), Introduction. Liquid-phase epitaxy (LPE) is a solution crystal growth technique for the deposition of crystallographically oriented thin films, thick layers, or discrete crystals on a seeding or template substrate.
of the impurity center together with the ground one E 2 is assumed. It is shown, that if the shift of E 1 and E 2 levels relatively to E c is characterized by the linear dependence on X, the fast relaxation appears near the point when E 1 level crosses E c and enters the energy gap.

Other readers will always. The isothermal rate of grain growth can be expressed by the phenomenological kinetic grain growth equation: G n = Dtexp(-E/RT) where G is the average grain size at time t, D is a constant, n is the kinetic grain growth exponent, E is the apparent activation energy, R is the gas constant, and T is the absolute temperature.

A2 was little affected by either deformation or magnetic field. In undeformed specimens A3 showed a sharp dip near E:= 2 x 4, resembling that predicted by Hikata and Elbaum.
In deformed specimens A3 was substantially larger, overtaking A2 near E;:= 3 X. Infrared Detectors Status and Trends5/5(1). Various numerical simulations are carried out for the melt convection and temperature distribution with and without the presence of a transverse magnetic field.
Numerical results show that magnetic damping can be effectively applied to stabilize melt flow, reduce turbulence and flow levels in the melt and over a certain threshold value a higher. For those currently in the field, this book can be used as a collection of useful data, as a guide to literature in the field, and as an overview of topics in the field.
The book also could be used as a reference for participants of educational short courses, such as those organized by SPIE. The book starts with two overview chapters. For those currently in the field, the book can be used as a collection of useful data, as a guide to the literature, and as an overview of topics covering a wide range of applications.
