Description
Summary:A study of persistent photoconductance has been investigated in a graphene ceramic. Graphene ceramic has been produced by using hot isostatic pressing of few-layer thick graphene nanoplatelets. The influence of laser beam power and wavelength was analyzed. A linear power dependence of photoconductance yield was observed as high as 129,5% for 1500 mW 975nm irradiation. The photocurrent changes were attributed to the photo-induced bolometric effect.
