Ion Implantation and Annealing of Oxides
(Materials Research Society, 1987)
Ion implantation damage and annealing results are presented for a number of crystalline oxides. In Al<sub>2</sub>O<sub>3</sub>, the amorphous phase produced by ion bombardment of the pure material first crystallizes in ...
Ion Implantation and Annealing of SrTiO3 and CaTiO3
(Materials Research Society, 1987)
Ion implantation damage and thermal annealing results are presented for single crystals of SrTiO<sub>3</sub> and CaTiO<sub>3</sub>. The near-surface region of both of these materials can be made amorphous by low doses ...
Aperiodic Stepwise Growth Model for the Velocity and Orientation Dependence of Solute Trapping
(Materials Research Society, 1987)
An atomistic model for the dependence on interface orientation and velocity v of the solute partition coefficient <i>k</i> during rapid solidification is developed in detail. Starting with a simple stepwise growth model, ...
Nonequilibrium Interface Kinetics During Rapid Solidification
(Materials Research Society, 1987)
The deviations from local equilibrium at a rapidly moving solid-liquid interface are well documented. The fraction of solute atoms in the liquid at the interface that joins the crystal during rapid solidification approaches ...
Transition-State Model for Entropy-Limited Freezing
(Materials Research Society, 1987)
A brief review is given of transition-state theory, both for the case of unimolecular reactions in the gas phase, and for reactions in condensed phases. An argument is made that, within the context of this theory, heterogeneous ...
