(a) Structural model
of monolayer β-In2Se3 in the (100) orientation.
(b) Three-part composite image
of an InSe nanoribbon inside a SWCNT, consisting of an AC-TEM image
(left), a simulated TEM image (center), and molecular model (right).
(c, d) Electron density profile maps in red, generated from the red
line superimposed over the experimental AC-TEM image in (b), and in
blue, generated from the blue line superimposed over the simulated
TEM image in (b), with calculated interatomic distances highlighted
in nm. (e–h) The same as (a–d), respectively, but for
a different nanoribbon in the (110) orientation.
