Effect of temperature on carrier transport and photoconductivity of Mn-doped FeS2 thin films
文献摘要：
Thin-film of Mn-doped iron disulfide(FeS2)has been prepared using the thermal evaporation method.This work reports the Hall measurements,temperature and light intensity-dependent photoconductivity,electrical transport mechanism,and photodetection properties of Mn-doped FeS2 thin film.The transient photoconductivity mea-surements of p-type Mn-doped FeS2 thin film show a consistent dependence upon temperature and light intensity.Charge transport mechanism was illustrated using different models.In region-Ⅰ(303-393 K)deposited film fol-lowed the thermally activated transport mechanism.Nearest neighbour hopping(NNH)transport mechanism was followed by region-Ⅱ(274-293 K),and Mott's variable range hopping(VRH)mechanism was dominant in region-Ⅲ(108-273 K).The fabricated device resulted in higher photoconductivity due to collecting charge carriers through electrodes under light illumination.The results also revealed that Mn-doped thin film possessed good photoresponsivity(～19 mA/W)as well as photo-detectivity(～3.4×1012 Jones)due to the occupation of localized states formed by Mn-doping.Light intensity-dependent photodetection properties suggested the po-tential for real-time photodetection applications.
