From: Stanene: Atomically Thick Free-standing Layer of 2D Hexagonal Tin
(a) HRTEM image of sample showing hexagonal lattice. The inset on the bottom left shows the EDAX spectrum from the same spot. Carbon and copper peaks arises from the TEM grid used. The middle inset shows large area TEM of stanene flake with layers. The inset on the extreme right shows the hexagonal electron diffraction pattern obtained from the sample confirming the presence of hexagonal lattice. (b) AFM image showing edge of ~4 layered stanene sheet. The inset on the bottom left shows height profile with several equal steps of height ~3.3 Å suggesting the interlayer separation. The inset at the top right shows a 3D view showing flake like structure.
