                         0.02 and x similar to 0.03 in the temperature range of 77K-300 K. 
                         The results show that sample with x similar to 0.02 presented 
                         negative photoconductivity effect in the whole range of 
                         temperatures measured, while sample with x similar to 0.03 
                         presented a transition from positive to negative 
                         photoconductivity. Hall measurements were also performed to 
                         investigate the effects observed in both samples, but could not 
                         give any conclusive explanation. On the other hand, we showed that 
                         disorder changes considerably the generation/recombination ratios 
                         as temperature is varied giving rise to the anomalous effects
