a Optical micrograph of a second exfoliated Te sample. The red circle indicates the region used for Raman spectroscopy. b AFM height and (c) tapping mode amplitude images of the region indicated by the black square in (a). d Height profiles along the red, orange, and green lines in (b), perpendicular to the c-axis direction for red and orange, parallel for green. The orange and green profiles are offset vertically for clarity
