Abstract

We show that reflectivity measurements enable the determination of the thickness of multilayered graphene on a metal substrate. The developed technique is based on comparison of the substrate reflectance with and without graphene and relies on the strong absorbance of graphene and high refractive index contrast. We demonstrate the technique by measuring the thickness of the CVD graphene film grown on a copper substrate.

Fig. 1
Fig. 1

Measured (dotted line) and calculated using data from [15] (solid line) reflectance spectrum of the copper foil.

Fig. 2
Fig. 2

Temporal evolution of the reflectance of the copper foil etched in acetic acid. One can observe that the reflectivity decreases by 3% at 400 nm and less than 1% at 600 nm during 10 min after oxide removal.

Fig. 3
Fig. 3

The measured (dots) and the calculated (solid lines) differential reflectance spectra of the films comprising of 1, 2, 3 and 4 graphene layers. The experimental data at each wavelength are averaged over ten points on the substrate surface. One can observe that variation in the film thickness over substrate surface is less than one graphene layer.

(a) Raman spectrum of multilayer graphene film transferred to a SiO2 substrate. Narrow G peak and a large ratio of 2D and D peaks indicate a high crystallinity of fabricated graphene. The shape and position of the 2D peak indicates that the film consists of 2-4 graphene layers [9,11]. (b) Transmittance of the graphene film transferred onto a SiO2 substrate measured relatively to the transmittance of the bare substrate. Results of the transmittance measurements for different points of the sample are shown. Solid horizontal lines represent calculated transmittance of the graphene coated quartz substrate relatively to the transmittance of the bare substrate [20]. By comparing calculated data with than measured at 800 nm one can conclude that the film is comprised of about 2.6 layers.
