Kinetics of vacancy annealing upon time-linear heating applied to dilatometry

A kinetic model for the diffusion-controlled annealing of excess vacancies under the experimentally relevant, non-isothermal condition of time-linear heating is presented and applied to dilatometry. The evolution of the vacancy concentration with time is quantitatively analyzed, considering as ideal sinks either dislocations or grain boundaries of spherical- or cylindrical-shaped crystallites. ...

Exergy Optimization Applied to Linear Parabolic

A new method of optimization on linear parabolic solar collectors using exergy analysis is presented. A comprehensive mathematical modeling of thermal and optical performance is simulated and geometrical and thermodynamic parameters were assumed as optimization variables. By applying a derived expression for exergy efficiency, exergy losses were generated and the optimum design and operating co...

Annealing kinetics of vacancy-related defects in low-dose MeV self-ion-implanted n-type silicon

Silicon samples of n-type have been implanted at room temperature with 5.6-MeV Si ions to a dose of 2310 cm and then annealed at temperatures from 100 to 380 °C. Both isothermal and isochronal treatments were performed and the annealing kinetics of the prominent divacancy (V2) and vacancy-oxygen ~VO! centers were studied in detail using deep-level transient spectroscopy. The decrease of V2 cent...
