mg mL− 1, with yields of up to 4 wt% monolayers. This process relies on low‐power
sonication for long times, up to 460 h. Transmission electron microscopy shows the
sonication to reduce the flake size, with flake dimensions scaling as t− 1/2. However, the
mean flake length remains above 1 µm for all sonication times studied. Raman spectroscopy
shows defects are introduced by the sonication process. However, detailed analysis …
