Abstract
In this work, in order to enhance the sensing capability of bare graphene, nickel phthalocyanine (NiPc) powder has been sublimated through a ther- mal evaporator in ultra-high vacuum, and deposited as a monolayer on a graphene on silicon carbide substrate. After characterization, the functionalized sample and a bare graphene layer have been settled on a properly designed platform, able to monitor the sensor response of both chemiresistors, allowing for a direct compar- ison of their performances under the same working condition. The results clearly demonstrate that the NiPc functionalization improves the response of bare graphene to ammonia and nitrogen dioxide by 40% and 30%, respectively, at 10 ppm concen- tration.
