This study demonstrates that the graphene work function can be increased by adding a layer of molybdenum or rhenium oxides, and a single layer of MoO3-x can also increase the work function of graphene. This provides potential for practical applications of graphene in electronics.
The electrodes used for flexible photovoltaic cells require materials that are transparent, conductive and flexible. All these features seem to be met by graphene, on the basis of which we were able to construct the anode. Here we show that increase of the graphene work function is possible using an additional layer of molybdenum or rhenium oxides. Moreover, we show that a single crystalline layer of MoO3-x can increase the work function of the graphene. In consequence there is a real chance for practical applications of graphene in electronics.
