Abstract
Defects arising from classical thermal annealing, electrical characteristics and dynamic resistance of silicon diode has been tried to treated by annealing with pulsed CO2 (λ= 10.6 µm) with pulse energy ranged from 500 to 600 mJ. Each diode was exposed to 5 pulses. The results showed an improvement in the behaviour of I-V characteristics curve of the diodes and reduction in its dynamic resistance.
