31	Lithium precipitation in fast-neution irradiated ultra-pure germanium Bendsen, C. Niel 03 June 2011 (has links) Various samples of ultra-pure germanium were lithium diffused for approximately one day at temperatures ranging from 300° to 4500 C under an inert atmosphere. Lithium precipitation kinetics were characterized utilizing D-C electrical conductivity measurements at room temperature. Selected samples were subsequently exposed to an estimated total integratedfast-neutron flux of order 1012 /cm2. Following the irradiation process, lithium precipitation subsequent to annealing at various temperatures was studied, again through the eletrical conductivity. It was noted that the presence of the fast-neutron generated disordered regions can initiate precipitation in lithium -diffused germanium in which no post-diffusion precipitation was observed.Utilizing Frank S. Ham's Theory of Diffusion -Limited Precipitation for spherical precipitate centers, and the precipitation kinetics data obtained, the density of precipitate centers was calculated as a function of annealing temperature. The variations in the density of precipitate centers with annealing temperature suggest this method as possibly useful in studies of annealing behavior of disordered regions in germanium.Ball State UniversityMuncie, IN 47306 Lithium.
