Cut from a single block of gneiss, the figure stands 57 feet (17.5 metres) high and is one of the largest freestanding images in the world.
(d) SEM image of freestanding silicon wires with three different spacings.
Comparing with the image of freestanding buckled triangular boron sheet shown in Fig. 5a, the unit cell of STM image of buckled triangular boron sheet on the Ag(111) surface increases to three times.
Figure 2b shows the 60-period epitaxial grating grown on 1,020 nm period suspended HfO2 grating with the air opening of 400 nm, and the inset is the zoom-in image of freestanding III-nitride grating.
Different from the image of freestanding β12 sheet shown in Fig. 5b, the bright spots come from the pz orbits of the boron atoms in the center of hexagons.
Figure 4 shows images of freestanding liquid metal structures resting on a substrate.
Painters who get the urge to break into three dimensions often do so halfway, by turning their two-dimensional images into freestanding but still basically flat cutouts.

Optical and SEM images of freestanding cantilever beam are presented in Fig. 7d, e, respectively.
