Determining the thickness of two-dimensional (2D) materials accurately and reliably is highly necessary for multiple investigations, but at the same time it can be quite complex. Most studies in this field measure a topographic map at the edge of the 2D material using an atomic force microscope (AFM), and plot a single-line cross-section using the software of the AFM. However, this method is highly inaccurate and can result in high relative errors due to surface roughness and line-to-line variability. This is even more important in ultrathin (
