Abstract
We present the synthesis and properties of iodine incorporated amorphous carbon films. Optical studies depict a decrease in band gap with variation in iodine content and pyrolysis temperature. Tuning of the metal-insulator transition is achieved by varying the pyrolysis temperature and iodine concentration. Appreciable decrease in magnetoresistance is observed with iodine incorporation, but negative magnetoresistance typical behavior of metallic samples is not witnessed.
