Figure 2: Structural characterization of ReS2.
From: Monolayer behaviour in bulk ReS2 due to electronic and vibrational decoupling

(a) HRTEM images taken from ReS2 along in- and out-of-plane directions. There are two flakes: one flake’s basal plane is perpendicular to the electron beam (red square box) and the other flake’s basal plane is oriented parallel to the beam (green square box). Scale bar, 20 nm. (b) Fast Fourier transform images from the denoted red/green windows. (c) Simulated kinematic diffraction patterns, and (d) nano-beam electron diffraction pattern. Inset: Zoom-in image to the nano-beam electron diffraction pattern.
