　　Graphene,with ultra-high carrier mobility and short photocarrier lifetime,has shown remarkable potential in ultrafast photodetection [1,2],though its photo-absorption(~2%)[3] and photoelectric response endure low values.The photo-response efficiency can be improved in a vertical stack of monolayer graphene and other two-dimensional(2D)atomic layers [4-6].
