摘要:

Comparative investigation of the process of the structure reordering of disordered implanted silicon layers after thermal (800°C, 30 min) and pulse laser annealing have been carried out. The new laser method of annealing implanted layers has a number of interesting features which provide great efficiency and locality of semiconductor doping without considerable heating of the base material and redistribution of implanted impurities. On the base analysing of investigation of kinetics of layer photostimulated recrystallization and calculation of temperature fields the possible mechanisms of laser annealing are also discussed.

摘要:

Stage III annealing kinetics have been studied for pure and radiation-doped copper, the latter containing a high concentration of interstitial and vacancy clusters which act as efficient sinks for mobile vacancies in stage III. In the doped samples, the influence of secondary defects such as divacancies on the annealing kinetics is suppressed, and the measured activation energy, 0.70 ± 0.03, must be interpreted as the migration energy of single vacancies. In undoped samples the same activation energy is found although the formation of vacancy clusters in stage III indicates that highly mobile and tightly bound di- or multiple vacancies are also present. This is consistent since the present method of activation energy determination cannot reveal an influence of highly mobile divacancies. Such an influence can be important to explain the observed second order dose shift of stage III for undoped samples.

摘要:

Quantitative analysis of the formation, reactivity and stabilization of radiation products in sodium metaphosphate glasses doped with active solutes (Cd2+, Pb2+, I−) makes it possible to determine the absorption of these products in terms of molar absorptivities, to compare their spectra quantitatively with results in other media, and to consider their possible use in dosimetry.

摘要:

The production of damage in pure and alloyed copper as a result of electron irradiation has been investigated by Wollenberger.1–3In contrast to the isolated Frenkel pairs produced by electron damage, fast neutron irradiation produces highly energetic recoil atoms which initiate large displacement cascades.
