6. Theoretical Studies of Defect Motion in Crystals.

Author

BROWN UNIV PROVIDENCE R I DIV OF ENGINEERING, Weiner,Jerome H., BROWN UNIV PROVIDENCE R I DIV OF ENGINEERING, and Weiner,Jerome H.

Abstract

A final technical report on the work done under the Grant is presented. The principal accomplishments described are: (1) The development of a new quantum rate theory for the motion of defects in crystals which includes thermal activation and quantum mechanical tunneling on an equal footing. (2) The development of a new method for the numerical solution of the time-dependent Schrodinger equation which is substantially faster (by a factor of about 30) than previously available methods.

7. THEORETICAL STUDIES OF DEFECT MOTION IN CRYSTALS.

Author

COLUMBIA UNIV NEW YORK DEPT OF MECHANICAL ENGINEERING, Weiner,Jerome H., COLUMBIA UNIV NEW YORK DEPT OF MECHANICAL ENGINEERING, and Weiner,Jerome H.

Abstract

The principal accomplishments described are: (1) A new formulation for rate processes in solids which does not make the assumption of thermal equilibrium among saddle-point configurations. (2) The extension of this formulation to include the effect of quantum statistics. (3) Development of techniques for the computer simulation of thermal equilibrium characteristics in linear-chain models of crystals containing vacancies. (Author)
