Effects of Experimental Parameters on Thermoluminescence of a Type II-a Diamond
Author: Albert D. Johnson
Publisher:
ISBN:
Category : Crystals
Languages : en
Pages : 42
Book Description
Thermoluminescence provides a method for studying properties of those crystalline imperfections which behave as electron traps and recombination centers in wide bandgap materials. This approach, however, has been used relatively little, possibly due to the fact that the shapes and intensities of thermoluminescent glow curves are functions of several experimental parameters and are often complicated by the overlapping of a number of individual glow peaks. In the present work, experimental parameters were isolated and some of their effects on thermoluminescent glow curves were analyzed. This yielded information on activation energies associated with trapping levels, the nature of the kinetics involved in electron transitions, and electron retrapping. A Type II-a diamond, which has a wide distribution of thermoluminescent glow peaks, was used in this work. (Author).

A Discussion of the Wheeler-Feynman Absorber Theory of Radiation
Author: Ronald G. Newburgh
Publisher:
ISBN:
Category : Absorption
Languages : en
Pages : 34
Book Description
The Wheeler-Feynman absorber theory of radiation is reviewed. A proof is offered to show that a sum of advanced and retarded effects from the absorber can provide the origin of radiative reaction. This proof is different from and perhaps simpler than that of Wheeler and Feynman. From arguments of momentum and energy conservation the necessity of the absorber for the emission of radiation is demonstrated for three cases. (Author).
